Leave Fredericton around 6:00 AM with coffee, water, and snacks already in the car; this is roughly an 11-hour driving day before sightseeing. Follow Route 2 into Québec, then Autoroute 20 west, with a practical fuel and breakfast break around Rivière-du-Loup. Continue toward Montréal and take the Highway 417 corridor through Ottawa toward Petawawa. The planned waterfront stop in Downtown Brockville works best as a tightly limited 30–45-minute leg stretch: park near the Brockville waterfront and walk along the river for views of the St. Lawrence and the Thousand Islands. Expect paid or time-limited street parking in the core, so don’t let this stop grow into a full lunch break.
Continue west to ByWard Market in Ottawa for about an hour. This is a convenient highway-break stop rather than a major detour, with casual counters, sandwich shops, bakeries, and international food generally running C$15–30 per person. Park in a nearby garage—street parking is scarce and enforcement is active—and keep the meal efficient, since you still have several hours to Petawawa. After lunch, rejoin Highway 417 west; traffic around Ottawa can slow significantly, especially near interchange construction, so rely on the car’s navigation for the final approach.
If you are still alert and daylight remains, stop at Bonnechere Provincial Park near Eganville for about an hour. Use it as a quiet lakeside reset rather than a full park visit; check the park’s day-use status and fees before leaving Ottawa, as late-season services can be reduced. From there, continue to Petawawa, check in, and make Petawawa Point your final outing. The waterfront is ideal for a 45-minute sunset walk along the Ottawa River—bring a light layer, as evenings can cool quickly. Keep dinner simple near your accommodation and refuel tonight; tomorrow’s Highway 17 run to Sault Ste. Marie is another full driving day.
Leave Petawawa around 6:00 AM and settle in for the long drive west on Highway 17. This is a full 10.5–11.5-hour day, so treat the route stops as leg-stretch breaks rather than trying to turn the drive into a relaxed sightseeing day. Keep the tank above half where possible, carry water and snacks, and expect long stretches with limited services. After roughly four hours, stop at Chutes Provincial Park near Massey for about 45 minutes: the waterfall lookout and short trail are an excellent quick reset, with a modest day-use or parking fee sometimes applying. Check seasonal access and trail conditions before leaving, as provincial-park facilities can be reduced late in the season.
Continue west toward Lake Superior Provincial Park, allowing another several hours of driving and a quick fuel or coffee stop around Espanola or Blind River if needed. Near the park, spend about 1.5 hours at a shoreline access point for the big, exposed views of Lake Superior—this is one of the few stops on the day worth slowing down for. Bring a light jacket even in August: the lake can make the shore noticeably cooler and windy, and mosquitoes may still be present around wooded trails. Park only in signed areas and avoid counting on reliable mobile service inside the park.
Make the final run to Wawa, where the Wawa Goose makes an easy 20-minute roadside photo stop and a useful final break before Sault Ste. Marie. From there, allow roughly 2.5 hours to town, arriving tired, so skip additional detours and go straight to Aurora Borealis Restaurant for dinner. Expect a casual meal of about C$20–35 per person; call ahead if arriving after 8:00 PM, since hours can vary and the long-distance-driving day may push dinner late. Afterward, check into your accommodation and refuel the car for the next morning—there is little benefit to sightseeing tonight after such a demanding route.
Leave Sault Ste. Marie around 6:30 AM on Highway 17, with a full tank, coffee, and food packed—services become widely spaced along Lake Superior. This is a demanding 9.5–10.5-hour drive, so treat Old Woman Bay in Lake Superior Provincial Park as your first proper break rather than trying to rush through. The signed viewpoint is just off the highway and gives you one of the finest roadside views in northern Ontario: the dark cliffs of Katherine Cove rising above the blue lake. Allow about 45 minutes, and check weather and road conditions before leaving; washrooms and cell service can be limited along this stretch.
Continue west on Highway 17 to Aguasabon Falls & Gorge in Terrace Bay, roughly 45 minutes from the highway. The short walk from the parking area leads to viewing platforms over the dramatic gorge and waterfall, a welcome chance to stretch after the morning’s driving. Plan about 45 minutes here. Bring a jacket even in August—the gorge can feel cool—and keep a little extra time in hand for construction, wildlife, or slower traffic on the winding sections of the Trans-Canada.
Near Thunder Bay, stop at Kakabeka Falls Provincial Park before heading into town. The main falls loop takes about an hour and is an easy, worthwhile finish to the driving day; the boardwalk viewpoints are close to the parking area, though stairs and uneven surfaces make sturdy shoes useful. Check the park’s day-use fee and closing details before departure, as seasonal hours and access can change. From the falls, allow roughly 25 minutes to downtown Thunder Bay. Finish at The Sovereign Room on Red River Road, a relaxed downtown spot for dinner and a drink; budget about C$25–45 per person, and arriving before the evening rush is sensible after such a long day. If you are staying outside downtown, use the car rather than attempting a late walk—the city is spread out and you will likely be ready for an early night.
Leave Thunder Bay around 6:30 AM on Highway 17, then connect with Highway 1 west toward Winnipeg. The first stop is the Terry Fox Monument, about 20 minutes east of town on Highway 17; allow roughly 30 minutes for the memorial and broad Lake Superior overlook. It is exposed and often windy, so keep a jacket accessible. Afterward, continue through the forested Trans-Canada Highway corridor, filling up whenever the tank drops below half and carrying lunch or substantial snacks—services become less frequent west of Kenora.
Break at Rushing River Provincial Park, just east of Kenora, around midday. The park’s short lakeside paths and rocky shoreline are ideal for a one-hour leg stretch, and a picnic is much easier than losing time waiting for a roadside restaurant. Day-use access is generally around C$12–20 per vehicle, though exact fees and availability can vary; use the official provincial-park listing before departure. From Rushing River, expect roughly 2.5–3 hours to Winnipeg, with the road becoming more open as you cross into Manitoba. On arrival, park at your hotel or use the paid lots around The Forks rather than trying to street-park downtown.
Head first to the Canadian Museum for Human Rights at The Forks for about two hours. Its galleries are a welcome indoor reset after the long drive, but check the timed-entry schedule before leaving Thunder Bay; adult admission is typically about C$25–30, and late-afternoon entry can sell out in summer. Afterward, walk a few minutes through The Forks to The Forks Market for dinner and browsing. Food-hall meals generally run C$15–30 per person, with plenty of casual choices; allow another 1.5 hours to eat, look through the small shops, and take a short riverside walk if you still have energy. Expect to arrive in Winnipeg in the late afternoon or early evening, depending on stops and traffic.
Leave Winnipeg around 6:30 AM and follow the Trans-Canada Highway 1 west toward Brandon, allowing roughly 7.5–8 hours of total driving to Regina. Keep the morning practical: stop for fuel and coffee around Brandon, then again near Moosomin, where services are useful before the long Saskatchewan stretch. The highway is straightforward, but watch for fast-moving traffic, construction zones, and changing weather; keep the tank comfortably above half when convenient.
Your first proper break is the Brandon Riverbank Discovery Centre, beside the Assiniboine River. Allow about 45 minutes to stretch your legs along the riverfront and use the facilities; check the centre’s seasonal hours before leaving, as they can vary. From there, it is a short drive into central Brandon for the Daly House Museum, a compact heritage museum in a beautifully preserved historic home. Plan about an hour, and confirm opening hours in advance—late-August hours are generally daytime and seasonal. The museum provides a worthwhile glimpse into Brandon’s early civic and domestic history without turning the stop into a lengthy detour.
Continue west on Highway 1 toward Regina, arriving in the late afternoon after the open prairie drive. Once checked in, head to the Saskatchewan Legislative Building in Wascana Centre; the grounds are especially pleasant in the softer evening light, and the exterior is accessible for a relaxed walk even if interior tours have ended. Allow about an hour to wander around the building, gardens, and nearby lake paths. It is roughly a 10–15-minute drive from most central Regina hotels, with parking available around Wascana Centre—follow posted restrictions and avoid assuming every lot is free.
For dinner, go to Caraway Grill, a dependable choice for Indian and South Asian dishes, with most meals costing about C$20–35 per person. Portions are generous, so sharing a curry, biryani, and naan works well after a full driving day. Reserve or check the evening hours before setting out, then keep the rest of the night quiet: tomorrow is another early start, and Regina’s central streets and Wascana Centre are better enjoyed without rushing.
Leave Regina around 6:00 AM on the Trans-Canada Highway 1, allowing 8.5–9.5 hours of driving once stops are included. This is mostly an efficient prairie crossing, so start with a full tank and breakfast in the car; fuel and services are straightforward around Moose Jaw, Medicine Hat, and Brooks. Your first proper break is the Medicine Hat Clay Industries National Historic District, reached in the late morning. Give yourself about 45 minutes to look around the surviving brickworks and industrial heritage buildings—an easy, compact stop rather than a major detour. Keep an eye on the clock, as Calgary is still several hours away.
Continue west on Highway 1 toward Brooks, then make the short detour to the Brooks Aqueduct National and Provincial Historic Site. Allow around 45 minutes for the enormous concrete irrigation structure and its interpretive signage; it is exposed and usually windy, with little shade, so bring water and sun protection. Admission is generally free, but conditions and access can vary, so check the provincial parks listing before leaving Medicine Hat. From here, plan on roughly two hours to Calgary, with the route becoming busier as you approach the city. If you are staying downtown, check in and leave the car parked—central Calgary is much easier to explore on foot or by CTrain than by driving.
After a long road day, head to the Calgary Tower for about an hour of skyline views. It is in the downtown core and convenient from most central hotels; admission is typically around C$25–35, and evening hours often extend beyond dinner, though booking ahead is wise in summer. The glass observation area gives you a useful orientation to Downtown Calgary, the Bow River, and the mountains to the west. Afterwards, walk or take a short rideshare south to Ten Foot Henry in the Beltline for dinner. Expect roughly C$30–50 per person before drinks; the vegetable-forward menu is particularly good after a day of highway food. Reservations are strongly recommended, especially on a Saturday night, and after dinner it is worth wandering a few blocks along 12 Avenue SW before turning in.
Leave Calgary around 5:30 AM on Highway 1 through Banff National Park. This is a very full driving day—roughly 10.5–11.5 hours—so have breakfast, water, and lunch packed, and check 511 Alberta and Parks Canada road conditions before departing. Arrive at Lake Louise early, ideally around 8:00 AM, before parking fills; the lakeshore viewpoint and a short walk along the shoreline take about 1.5 hours. Parking is limited and paid during the busy season, so do not linger if the lot is full. Continue to Moraine Lake only with a reserved Parks Canada shuttle or another approved access option; private vehicle access is restricted, and the shuttle ride adds time. Allow about 1.5 hours for the lakeshore viewpoint and the easy Rockpile-area walk.
Continue west through Yoho National Park to Emerald Lake, crossing into British Columbia and allowing extra time for construction, wildlife, and summer traffic. The lakeshore trail is a good one-hour stretch after the morning’s driving, with especially fine views from the dock and eastern shoreline. Keep fuel topped up whenever convenient—services become more widely spaced after the mountain parks—and avoid counting on a quick restaurant stop for lunch. A packed meal is far more reliable, particularly with the fixed shuttle timing at Moraine Lake. From Emerald Lake, follow Highway 1 toward Golden, then take Highway 5 south toward Kamloops; expect to arrive tired in the evening rather than with much time for additional sightseeing.
After checking in, have dinner at The Noble Pig Brewhouse in central Kamloops, a practical choice near downtown hotels with substantial pub food and house beer. Budget roughly C$25–45 per person, and check the current closing time before setting out because arrival may be late. If you still have energy afterward, take a brief walk along Victoria Street or the nearby Thompson River waterfront, but prioritize sleep: tomorrow’s drive to Vancouver is shorter, yet leaving around 7:00 AM helps avoid the worst traffic approaching Hope and the Lower Mainland.
Leave Kamloops around 7:00 AM with coffee, water, and a proper breakfast packed. Take Highway 5 south toward Hope, then continue toward Highway 1; the drive is usually about 4.5–5.5 hours, but construction and Vancouver-area traffic can add time. Your first worthwhile stop is Othello Tunnels in Coquihalla Canyon Provincial Park, roughly 1.5 hours before continuing west. The old railway-grade trail passes through dramatic granite canyon walls and several short tunnels; allow about 1.5 hours, wear shoes with decent grip, and check BC Parks conditions before leaving because access or tunnel sections can occasionally be restricted. Parking is limited, so arriving in the morning is a real advantage.
Continue west via Highway 1 to Fort Langley National Historic Site, allowing roughly an hour depending on traffic around Chilliwack and Abbotsford. Spend about 1.5 hours wandering the reconstructed trading-post buildings, courtyard, and riverside village streets. Admission is generally around C$10–15 per adult, and summer hours are commonly approximately 10:00 AM–5:00 PM, though verify the 2026 schedule before setting out. Fort Langley is a good place to slow the pace after the mountain drive—grab a coffee or small bite on Glover Road if you need one, then continue toward Vancouver. From Fort Langley, allow roughly 45–75 minutes to Granville Island, depending heavily on bridge traffic; parking there is available but fills quickly, and the Aquabus or a short walk from nearby False Creek parking can be easier than circling.
Spend about 1.5 hours at Granville Island Public Market, browsing produce, baked goods, seafood, and prepared-food counters. It is ideal for a late lunch or grazing stop at around C$15–30 per person; most market activity winds down in the early evening, so arriving before 4:30 PM is preferable. Afterwards, drive or take the Aquabus across False Creek, then head to English Bay Beach in the West End for sunset. Street parking is competitive and often metered, so a garage or transit connection is less stressful; from Granville Island, the Aquabus to Hornby Street followed by a roughly 15-minute walk is a pleasant option. Bring a light layer—August evenings by the water can feel cool—and stay for the views toward the North Shore Mountains before checking into your Vancouver accommodation.
This is the one day where the itinerary’s selected stops do not realistically fit the stated transport plan. The planned Highway 1 eastbound drive from Vancouver to Calgary takes roughly 10.5–12 hours in good conditions, while Bridal Veil Falls Provincial Park, Revelstoke Railway Museum, Rogers Pass National Historic Site, and dinner at River Café add several hours and detours. To attempt the full list, leave Vancouver by about 4:00 AM, with fuel, coffee, breakfast, and lunch packed. Take Highway 1 through Hope toward Chilliwack; Bridal Veil Falls Provincial Park is a short detour from the highway, and the waterfall walk typically takes about 30 minutes. Check trail and parking conditions before leaving—parking is limited, and the trail can be muddy after rain.
Continue east through Hope, Manning Park country, Revelstoke, and Golden, allowing extra time for construction, mountain weather, wildlife, and fuel stops. The Revelstoke Railway Museum is an excellent practical break: plan about 1.5 hours, with admission generally around C$20–30 for adults; hours are seasonal, so verify the day’s closing time before committing to the stop. From there, continue through Glacier National Park to Rogers Pass National Historic Site, where 45 minutes is enough for the interpretive displays and a short mountain-side pause. Do not linger on roadside pullouts, and keep bear-safety rules in mind—wildlife sightings are common, but stopping in unsafe locations is not worth it.
From Rogers Pass, the remaining drive to Calgary is still several hours, including the descent through Golden and the approach via Lake Louise and Banff National Park. In practice, arriving in time for dinner at River Café in Prince’s Island Park is unlikely if all three stops are retained. If the dinner reservation matters, reserve a late seating—around 9:00 PM or later—and call ahead to confirm the kitchen can accommodate the delayed arrival; dinner is usually about C$40–70 per person, and the restaurant is reached via the park’s pedestrian paths rather than direct street parking. The safer version of this day is to treat Bridal Veil Falls Provincial Park, Revelstoke Railway Museum, and Rogers Pass National Historic Site as brief photo-and-stretch stops, skip any unscheduled sightseeing, and expect a very late arrival in Calgary.
Leave Calgary around 6:00 AM on Trans-Canada Highway 1 for the practical west-to-east run toward Regina. The drive is roughly 8.5–9.5 hours without extended stops, but today’s selected detour makes it longer, so pack breakfast and expect a late arrival. The first stop is the Head-Smashed-In Buffalo Jump Interpretive Centre, near Fort Macleod—allow about 1.5 hours for the exhibits, Blackfoot cultural interpretation, and the striking prairie setting. It opens seasonally in the morning; check the official schedule before leaving, and budget roughly C$15–20 per adult. From Calgary, allow about two hours to reach the site, with straightforward parking on arrival.
Continue east to the Medicine Hat Saamis Tepee, allowing roughly two hours from Head-Smashed-In Buffalo Jump depending on road conditions. The landmark is beside Saamis Archaeological Site and is best treated as a short leg-stretch stop—about 30 minutes for photographs and the nearby viewpoint. Fuel, coffee, and a proper lunch are easiest to arrange in Medicine Hat before rejoining Highway 1; services become less convenient once you are back on the open prairie. From there, continue toward Moose Jaw, another roughly three hours east. The Tunnels of Moose Jaw are a worthwhile late-afternoon stop, but book a guided tour ahead if possible: tours generally run about 1.5 hours and cost approximately C$20–30 per adult. Arrive with enough margin for the final tour of the day, as this attraction does not work well as a casual drop-in after closing.
Finish the drive to Regina, usually about 45 minutes from Moose Jaw, and have dinner at The Willow on Wascana, near Wascana Centre. It is a good place to finally slow down after the long highway day, with a comfortable dinner budget of about C$25–45 per person before drinks and tip. Confirm the evening hours and reserve if arriving during the dinner rush. Afterward, keep the evening simple: check into your accommodation, refuel the car if needed, and avoid adding a walk around Wascana Centre unless you arrive with energy—tomorrow’s schedule is another early start.
Leave Regina around 6:00 AM on the Trans-Canada Highway 1, with Moosomin as the first practical fuel and coffee stop and Brandon as the better place for a proper break or early lunch. The drive to Winnipeg is about 7.5–8.5 hours before sightseeing, so keep the tank comfortably above half and expect long, open prairie stretches. The planned RCMP Heritage Centre and Western Development Museum are best treated as route stops rather than a leisurely Regina day: visit the RCMP Heritage Centre first for about 1.5 hours, then continue toward Moose Jaw for the Western Development Museum, allowing another 1.5 hours. Check same-day hours before leaving—both museums generally operate daytime hours, with admission commonly around C$15–25 per adult.
After the museum, continue west on Highway 1 toward Winnipeg; with the museum visit and breaks, arrival is likely late afternoon or early evening. Check into your accommodation, then drive or take a rideshare to Assiniboine Park for an easy one-hour walk through the gardens and park paths. It is a good decompression stop after the prairie crossing, but don’t linger past dusk if you still need to reach dinner. From the park, allow roughly 15–25 minutes by car to the Exchange District, depending on traffic, and finish at Clementine. Their compact, well-regarded menu is ideal after a long driving day, with dinner usually around C$20–35 per person; evening hours can vary, so verify the closing time before setting out. Parking is easier in the Exchange District after business hours, though a rideshare avoids the hassle of finding a spot.
Leave Winnipeg around 6:00 AM for the long eastbound run on the Trans-Canada Highway 1, joining Highway 17 toward Thunder Bay. It is an 8.5–9.5-hour driving day before meaningful stops, so pack breakfast and keep the morning efficient. The planned morning visit to Lower Fort Garry National Historic Site in St. Andrews is not realistically compatible with this route and arrival time—it lies north of Winnipeg and would add a substantial detour—so treat it as an optional extra only if you are prepared to leave much earlier and accept a late Thunder Bay arrival. For the practical itinerary, continue east and plan a proper meal, fuel, and washroom stop in Kenora, roughly halfway through the day; services are reliable there, but do not assume every smaller roadside stop will be open or well stocked.
Use Lake of the Woods in Kenora as your main break: allow about an hour for a waterfront walk, fresh air, and a reset after the prairie driving. McLeod Park and the Harbourfront area are convenient for stretching your legs, with benches, views across the water, and nearby cafés and fast-casual restaurants if you prefer not to eat in the car. Keep an eye on the clock—this is a restorative stop rather than a long sightseeing visit, and you still have several hours of winding highway ahead through northern Ontario. Fill the tank in Kenora before continuing; fuel opportunities become more spread out as you approach Thunder Bay.
After checking in and dropping your bags in Thunder Bay, head to Trowbridge Falls for an easy one-hour forest-and-waterfall walk. The trails are generally best enjoyed in daylight, and the rocks beside the falls can be slippery, so wear shoes with decent grip and avoid lingering if you arrive close to sunset. From there, drive back toward the city for dinner at Nortenos Taqueria, where tacos and other Mexican plates usually run about C$20–35 per person before drinks and tip. After such a long highway day, this is enough evening activity: eat, refuel, and turn in early rather than adding another attraction. Check the restaurant’s current hours before setting out, since late arrivals after the waterfall walk may fall near closing time.
Leave Thunder Bay around 6:00 AM with a full tank, coffee, and breakfast packed; Highway 17 to Sault Ste. Marie is a demanding 9.5–10.5-hour run, and services become increasingly spaced out along the north shore of Lake Superior. Your first proper stop is Neys Provincial Park, near Marathon, roughly two hours east of Thunder Bay. Allow about an hour to stretch your legs on the beach and walk around the historic-site surroundings. The day-use area is generally open from morning through evening in summer, though a day-use or parking fee may apply; keep the stop short, since you still have a long stretch ahead.
Continue east on Highway 17 toward White River, using Marathon or Schreiber for fuel and a quick washroom break. Around midday, stop at the White River Heritage Museum for approximately 45 minutes. This small museum tells the local story behind Winnie-the-Pooh, whose real-life inspiration was a bear cub purchased in White River during the First World War, alongside exhibits on railway and northern community history. Check the museum’s seasonal hours before leaving—summer hours are usually daytime-focused—and budget roughly C$5–10 for admission. White River is also a sensible place to top up fuel and buy something portable for the afternoon.
The final leg toward Sault Ste. Marie is scenic but tiring, so take another brief break near Wawa and watch carefully for wildlife, construction, and sudden weather changes. Before reaching town, make the planned late-afternoon stop at Batchawana Bay Provincial Park, north of Sault Ste. Marie, for about an hour. The broad beach is ideal for a quiet Lake Superior pause, but bring water, insect repellent, and a towel; facilities can be limited outside the main day-use areas, and the beach may feel cool even in August. From Batchawana Bay, allow roughly 45–60 minutes to reach Sault Ste. Marie, depending on traffic and road work. After checking in, finish at The Breakfast Pig Badass Eatery for dinner—a relaxed local-style choice where expect about C$20–35 per person. Because this is a long driving day, check current opening hours before setting out and avoid adding further sightseeing afterward.
This is an unusually ambitious day: the selected stops are in the opposite direction from your stated Sault Ste. Marie–to–Petawawa run, and visiting all of them makes the day substantially longer than 10–11 hours. If you keep the full plan, leave around 6:00 AM and treat Canadian Bushplane Heritage Centre as the first stop before getting onto Highway 17. The museum typically opens in the morning and takes about 1½ hours; allow roughly C$15–25 per adult, and verify the day’s hours before setting out. It is conveniently located near the waterfront, with on-site parking, but this stop should be brief if you want to preserve daylight for the long drive.
Continue east toward Sudbury, stopping for fuel and a proper break before visiting Dynamic Earth around midday. Set aside about 1½ hours and roughly C$20–30 per adult; the mining exhibits are especially worthwhile for understanding why Sudbury looks the way it does. The attraction has parking and is easiest by car, but check opening hours and timed-entry requirements in advance. Afterward, keep moving along Highway 17 through North Bay—use it as your main fuel, washroom, and food reset rather than adding another sightseeing stop.
The planned A.Y. Jackson Lookout near Wawa is a memorable pull-off, but it is far west of Petawawa and would require backtracking or a major detour on this particular day. If you retain it, allow 30 minutes for the short walk, photographs, and the broad Group of Seven landscape, and expect a very late arrival. A more realistic version of today is to skip the lookout and continue directly east, using North Bay and then the Deep River area for brief breaks. Keep the fuel tank comfortably above half—services are available along the corridor, but stretches can feel isolated after dark.
For dinner, Whitewater Brewing Company in Cobden is a good final stop before Petawawa, with casual food generally costing about C$25–45 per person. Check the kitchen closing time before committing, since a late departure from Sault Ste. Marie or extended stops at Dynamic Earth and A.Y. Jackson Lookout could put you there after service ends. From Cobden, it is roughly a 20–25-minute drive to Petawawa; arrange hotel check-in in advance and avoid any further sightseeing tonight.
Leave Petawawa around 6:00 AM for the long eastbound drive to Fredericton, following Highway 417 through Ottawa, then Autoroute 40/20 across Montréal, Québec, and toward Rivière-du-Loup before joining Route 2 in New Brunswick. Budget 10.5–11.5 hours of driving, plus fuel and meal stops, so the listed sightseeing stops in Gatineau, Ottawa, and Montréal are not realistically compatible with arriving in Fredericton the same evening. Treat this as a travel day: fuel around Ottawa and Rivière-du-Loup, and plan a proper meal near Montréal rather than trying to add several short breaks. Keep an eye on Québec construction and traffic around Montréal; downtown detours can easily add an hour.
If you still want to include the planned stops, they need to become a separate overnight itinerary rather than brief en-route visits. The Canadian Museum of History in Gatineau generally takes about 1.5 hours and is usually open into the late afternoon or early evening, while Parliament Hill is best treated as a one-hour outdoor stop; both require leaving the main route and then crossing back through the Ottawa area. Likewise, Old Montréal and Café Olimpico in Mile End are worthwhile only with a dedicated Montréal stay—the café is typically open from morning into the evening, but hours can vary. For this day, continue directly to Fredericton, check in, and have dinner near Downtown Fredericton or Queen Street after arrival; save the cultural stops for a future trip when you can enjoy them without turning an already demanding drive into an unsafe 14-hour day.
