Toronto to Montreal: Distance, Drive Time, and the 401 Weekend
About 542 kilometres on the fast route — five and a half hours if traffic cooperates, six and a half if Kingston becomes lunch, and a bilingual food reward at the end if you planned parking before the playlist.
Toronto to Montreal is the drive Eastern Canadian families treat as routine until construction, holiday traffic, or a forgotten winter tire appointment turns into a household logistics emergency.
The numbers first: mapping services and provincial tourism sources converge on about 542–550 km (337–342 miles) on the 401/A-20 fast route. Pure driving time lands near 5.5 hours when traffic is kind; Tourisme Montréal describes the straight point-A-to-B run at about 5.5 hours with only one or two quick stops. Real weekends run longer — a proper Kingston break and Montreal parking hunt easily push the day to 7 hours door-to-door.
The 401 is not scenic in the Big Sur sense. It is efficient: two major cities, two provinces, and enough food culture at the end to justify the kilometres. Chinese Canadian, South Asian, and Filipino GTA households do this run for family, festivals, McGill or UdeM visits, and long weekends.
Leave Markham after 4 p.m. on Friday and you donate an hour to brake lights before Kingston. Leave Saturday before 7 a.m. and the same road feels almost civilized until Montreal merge traffic appears on Autoroute 20.
Distance and drive time
- How far is Toronto from Montreal?
From downtown Toronto to downtown Montreal is roughly 542–550 km (about 337–342 miles) via Highway 401 east into Autoroute 20 — the route most mapping tools plot.
Straight-line distance is about 504 km. Road distance runs longer because the 401 follows the Lake Ontario and St. Lawrence corridor instead of cutting northeast across the map.
- ·Starting from Mississauga, Markham, or Scarborough adds about 10–25 km depending on how you merge onto the 401.
- ·The Thousand Islands / Route 138 scenic detour adds roughly 30–50 km versus the pure 401 run.
- How long does it take to drive from Toronto to Montreal?
Tourisme Montréal and most routing engines put pure highway time at about 5.5–6 hours in light traffic with only one or two quick stops.
All-day reality for families is usually 6.5–8 hours once you include a 45–60 minute Kingston break, fuel, and Montreal merge slowdowns.
- ·Friday 3–7 p.m. departures from the GTA often add 60–90 minutes through the Kingston corridor.
- ·Sunday 2–6 p.m. returns toward Toronto hit the same pinch points in reverse.
- ·Check Ontario 511 and Quebec 511 for construction before you leave.
- What is the best route from Toronto to Montreal?
There is no international border crossing on this domestic route — you stay in Canada the entire drive.
- ·Fastest: 401 east through Kingston and Cornwall, then Autoroute 20 into Montreal. Ontario limits are typically 100 km/h with select 110 km/h sections; much of A-20 in Quebec is 100 km/h.
- ·Scenic: exit near Gananoque for the Thousand Islands Parkway and Route 138 river roads, then rejoin the 401/A-20 toward Montreal. Budget an extra 45–90 minutes plus stop time.
- Is the Toronto to Montreal drive easy in winter?
The 401/A-20 run is predictable on paper — long straight highway, few surprises in routing. Weather east of Kingston is not predictable.
EV drivers should plan a DC fast-charging stop in Kingston or Cornwall and assume 20–40% cold-range loss on highway legs at winter speeds with heat on.
- ·Quebec law requires winter tires on passenger vehicles from December 1 through March 15.
- ·Ontario does not mandate winter tires province-wide, but all-season tires on lake-effect snow east of Kingston are a bad bet.
- ·See our winter EV ownership guide for cold-range planning on this corridor.
- How long does it take to drive from Montreal to Toronto?
Montreal to Toronto is the same 542–550 km west on Autoroute 20 and the 401. Routing is mirror-image; traffic patterns are not.
Sunday afternoon westbound volume toward the GTA is often the slowest window on the entire corridor.
- ·Plan the same 5.5–6.5 hour driving baseline you would eastbound.
- ·Add construction and weather buffer — especially if you leave Montreal after a late Sunday brunch.
Corridor stops worth planning
Verified businesses and landmarks along the 401/A-20 and scenic alternates. Hours change seasonally — confirm before you detour.
GTA exit through Oshawa: merge and first reset
Every Toronto departure starts with the same question: 401 express or collectors, and how angry is traffic already at Highway 400 or the 404 merge.
Fuel in the east GTA if you want fewer panicked stops later. Quebec gasoline pricing often runs higher than Ontario — filling before Cornwall is still a common habit.
- ONroute Oshawa (401). Official Highway 401 service centre with food court, restrooms, and EV fast charging at select ONroute locations via Ivy/Ivy Charge network.Recommended time: 15–25 minutes
- ONroute Trenton (401). Mid-corridor plaza east of Belleville — useful when Kingston still feels too far and kids do not.Recommended time: 15–20 minutes
Kingston: the halfway sanity stop
Kingston sits roughly 260 km from downtown Toronto on the 401 — almost exactly halfway to Montreal by distance, which is why it is the default break.
Downtown Kingston at Confederation Basin is walkable and calm compared to another hour of 401 hypnosis. EV drivers often DC-fast-charge here before pushing into Quebec.
- Confederation Basin / Kingston waterfront. City waterfront along Lake Ontario at the foot of Brock Street — public docks, walking paths, and spring-through-fall activity without a highway detour far off the 401 (Exit 632 / Division St south).Recommended time: 30–45 minutes
- Pan Chancho Bakery & Café. Long-running Kingston bakery and café on Princess Street — breakfast pastries, sandwiches, and coffee for a proper sit-down break.Recommended time: 45–60 minutesBest cars for long commutes →
- Fort Henry National Historic Site. Parks Canada fort above the St. Lawrence — worthwhile if your group wants history and views and you have not already lost the day to traffic.Recommended time: 90–120 minutes
Thousand Islands scenic detour (optional)
If you skip the pure 401 sprint, the Thousand Islands Parkway and Gananoque river towns break monotony. Budget extra time — this is not faster, it is prettier.
- Thousand Islands National Park (Mallorytown Landing). Parks Canada visitor centre off the 401 corridor — gateway to river islands and lookout trails.Recommended time: 45–75 minutes
- Gananoque downtown. Small river town east of Kingston — lunch, boat tour tickets, and a calmer pace than service-plaza food.Recommended time: 60–90 minutes
Cornwall and the Ontario–Quebec line
There is no customs stop on this domestic route, but language on signage shifts, fuel brands change, and Quebec traffic law applies the moment you cross the provincial line.
Use this stretch for a final Ontario fuel top-up or EV charge if your arrival plan in Montreal is tight.
- ONroute Ingleside (401, near Cornwall). Last major ONroute before Quebec — fuel, food, restrooms, and charging options depending on network status.Recommended time: 15–25 minutes
- Cornwall waterfront / Lamoureux Park. St. Lawrence riverfront park if passengers need grass and air before Autoroute 20 merges toward Montreal.Recommended time: 20–30 minutes
Montreal arrival: park once, then walk
Montreal rewards drivers who park once. Old Montreal, Chinatown, Mile End bagel shops, and Jean-Talon Market are easier on foot than by car on a Saturday evening.
Downtown garages fill on festival weekends — book parking or hotel garage access before you assume street spots exist.
- Chinatown Montreal (Rue de la Gauchetière). Compact district south of downtown — dim sum, noodles, and late dinner after a long 401 day. Weekends are busy; aim for early evening seating.Recommended time: 60–90 minutes for dinnerGTA region guide →
- Schwartz's Deli (Saint-Laurent Boulevard). Montreal smoked-meat institution — expect lines at peak meal times; counter service moves faster than sit-down expectations.Recommended time: 45–60 minutes
- St-Viateur Bagel / Fairmount Bagel (Mile End). Two legendary Montreal bagel shops in Mile End — hot bagels, short counter lines, and a neighbourhood walk that feels nothing like the 401.Recommended time: 30–45 minutes
- Jean-Talon Market. Large public market in Little Italy — produce, prepared food, and weekend energy. Closed Mondays; summer Saturdays are packed.Recommended time: 60–90 minutes
- Old Montreal / Place Jacques-Cartier. Historic riverfront core — cobblestones, Notre-Dame Basilica nearby, and slow tourist traffic. Park in a garage and walk in.Recommended time: 2–3 hours if first-time visitorsWinter EV ownership guide →
- Fairmont The Queen Elizabeth. Downtown Montreal landmark hotel connected to Gare Centrale — strong choice when you want garage parking and walkable downtown access.Recommended time: Overnight
- Hotel William Gray (Old Montreal). Boutique hotel in Old Montreal with on-site dining — alternative when you want Old Port walkability and valet parking.Recommended time: Overnight
Pro Tips
Consider these extra good-to-knows to make the most of your trip.
Best departure time
- ·Saturday before 7 a.m. from the GTA for lighter 401 traffic — saves roughly 30–60 minutes versus a 4 p.m. Friday start in many weeks
- ·Avoid Sunday 3–7 p.m. westbound returns toward Toronto unless you enjoy merge anxiety on the 401 near Kingston
- ·Check Ontario 511 and Quebec 511 for construction; summer lane reductions east of Toronto are common
Ideal vehicle type
- ·Comfortable crossover or sedan with quiet highway manners — see our long-commute buying guide for seat and assistance tests
- ·Winter tires required in Quebec Dec 1–Mar 15; all-wheel drive helps, it does not replace proper rubber
- ·EV works with Kingston/Cornwall DC stops; hybrid removes range stress for winter weekend trips
Where the drive gets annoying
- ·401 construction zones east of Toronto and through Kingston approaches
- ·Holiday long-weekend volume — Civic Holiday, Thanksgiving, and Christmas corridors
- ·Autoroute 20 merge into Montreal and downtown one-way confusion on arrival
Which car should you take?
This corridor rewards comfort, winter readiness, and cargo more than horsepower.
| Trip personality | Bring (or rent) | Why |
|---|---|---|
| Family festival weekend | Three-row SUV with winter tires | Kids, luggage, and grandparents who need easy entry at Kingston and Montreal garages |
| Montreal food crawl | Compact SUV or sedan | Tight Old Montreal parking — smaller footprint, quieter in garage ramps |
| Scenic Thousand Islands detour | Quiet highway cruiser | Extra kilometres feel better with lumbar support and a calm adaptive cruise |
Pick your version of the drive
Same cities, different goals. Pick the version that matches whether you want speed, scenery, or a food-first Montreal weekend.
The Fast 401 / A-20 Run
401 east with one Kingston stop and straight into Montreal on Autoroute 20. Best when you need to arrive before 7 p.m. dinner reservations.
Boring is a feature on this version. The goal is arrival energy, not Instagram overlooks.
- →ONroute Oshawa or Trenton — 15–25 min
- →Kingston waterfront or Pan Chancho — 45–60 min
- →Direct to Montreal hotel garage
The Thousand Islands Scenic Version
Exit toward Gananoque and the Thousand Islands Parkway for river views. Adds roughly 45–90 minutes plus stop time versus the pure 401 sprint.
Not ideal with toddlers who needed to be in Montreal two hours ago.
- →Thousand Islands National Park lookout — 45–75 min
- →Gananoque lunch — 60–90 min
- →Rejoin 401/A-20 toward Montreal
The Kingston Overnight Split
Stop in Kingston for dinner and a hotel if the group cannot do five hours straight. Makes Sunday return calmer too.
Popular with families visiting Queen's students or aging relatives halfway.
- →Kingston downtown dinner — 90 min
- →Morning coffee at Pan Chancho — 45 min
- →Montreal arrival mid-day
EV notes for Toronto to Montreal
The corridor is about 542–550 km — plan for one DC fast-charging stop minimum in winter, often two if you start below 90% state of charge. Ivy Charge / ONroute locations and Kingston-area DC hubs are common choices; verify live status in Flo, ChargePoint, or your OEM app before you rely on a single site.
Quebec electricity rates differ from Ontario time-of-use plans. Run our EV vs gas road trip and public vs home charging calculators with your actual kWh assumptions if you stay multiple nights in Montreal.
GTA condo drivers without Level 2 at home still do this trip — but it depends on a Kingston or Cornwall DC stop, not fantasy garage charging. Pair with our condo charging guide if you are deciding whether a full EV fits your life.
Compare corridor trip costs
Fuel pricing shifts at the Ontario–Quebec line; winter EV range does too. Run the calculator on your actual vehicle before the family debate starts.
The bottom line
Toronto to Montreal is long on highway hours and short on mystery. Match departure time, route version, and Montreal parking before you optimize the playlist.
Kingston at roughly the halfway kilometre mark is the difference between a tolerable drive and a miserable one — budget 45–60 minutes there even on the fast run.
The best corridor car is the one that keeps everyone calm at the Quebec line, meets winter-tire law when it applies, and still has range or fuel for the drive home Sunday.
