Markham to Downtown Toronto Commute: What Buyers Should Know

The short answer

• GO Trains on the Stouffville line connect Markham stations directly to Union Station in roughly 40 to 50 minutes, with no transfers.
• Driving is faster off-peak but far less predictable during rush hour, when the DVP and Highway 404 both slow down.
• Unionville GO is the busiest and best-connected station in Markham, with over 1,600 parking spaces and bus connections.
• Metrolinx is adding rush hour trips and working toward more frequent service on this corridor, which should help over time.
• Where you buy within Markham changes your actual commute more than the city name on the listing does.

How the GO Train commute actually works

Markham sits on the Stouffville GO line, which runs south through Scarborough and into Union Station in downtown Toronto. Stations along the Markham stretch include Unionville, Centennial, Mount Joy and Markham Village, among others and all of them run direct trains with no transfer required to reach Union.

Ride time from a Markham station to Union Station generally falls in the 40 to 50 minute range, with the exact number depending on which stop you board at and how many stations the train calls at along the way. That is the in-train portion only. Add time to get to the station, park or get dropped off and then walk from Union Station to your office and most commuters find the door-to-door trip runs closer to an hour each way.

This is a meaningfully different experience than driving the same distance, because the train takes roughly the same amount of time whether you catch an early departure or a later one. That consistency is a big part of why GO Train commuting is such a strong selling point for homes near a station.

Driving the Markham to downtown Toronto commute

The driving route generally means either Highway 404 south to the Don Valley Parkway or a combination with Highway 401, depending on where in Markham you start and where downtown you are headed. Off-peak, in the middle of a weekday or on a weekend, this drive can take as little as 35 to 45 minutes.

During weekday rush hour it is a different story. Both the 404 and the DVP are known for heavy congestion in the mornings and evenings and the same drive can stretch to 60, 75 or even 90 minutes when traffic is bad. Anyone who has driven the DVP at 8am on a weekday knows this isn’t an exaggeration, it is just the normal state of that road.

For buyers who need a car every day anyway, perhaps for a job that is not downtown or for picking up kids, driving remains a reasonable option and the unpredictability is just something to plan around. For a daily downtown commuter, though, the GO Train usually wins on reliability even when it does not win on raw speed.

Comparing GO Train and driving

Factor	GO Train (Stouffville line)	Driving (404 / DVP)
Typical travel time	40 to 50 minutes, fairly consistent	35 to 45 minutes off-peak, 60 to 90+ minutes in rush hour
Predictability	High, schedule-based	Low during peak hours
Cost structure	Distance-based fare, check current rates on GO Transit’s site, monthly pass available	Fuel, parking downtown, wear and vehicle cost
Parking at origin	Station lots (Unionville has roughly 1,600 spaces)	Not applicable
Frequency	Currently every couple of hours off-peak, more frequent at rush hour, with expansion underway	Available any time

Which Markham GO station matters most

Not every GO station along the Stouffville line offers the same experience and this is where buyers should pay attention when comparing neighbourhoods within Markham. Unionville GO is the largest and busiest station in the area, with a proper station building, about 1,620 parking spaces and connections to York Region Transit and Viva Rapid Transit buses that feed commuters in from surrounding streets.

Centennial, Mount Joy, Markham Village and other stops along the line serve their own pockets of the city and some have seen recent upgrades as part of Metrolinx’s broader expansion work. Milliken and Agincourt stations, just south of Markham in Scarborough, have also had completed upgrades, which benefits Markham residents who sometimes find it easier to drive a few minutes south to catch a train there.

For a buyer, the practical question is rarely “does Markham have GO access” but rather “how many minutes am I from the specific station I’d actually use.” A home a 5-minute walk from Unionville GO and a home a 20-minute drive from the nearest station can carry very different day-to-day realities even though both are technically in Markham.

What GO Transit expansion means for future commutes

Metrolinx has been actively expanding service on the Stouffville line, which directly affects the markham to downtown toronto commute for anyone buying with a multi-year horizon in mind. Recent additions include new rush hour trips between Unionville GO and Union Station and station upgrades completed at Agincourt, Milliken, Old Elm and Unionville.

The stated longer-term goal for this corridor is service every 15 minutes or better between Union Station and Unionville GO, which would be a significant change from the current schedule of a train every couple of hours during off-peak periods. Corridor work including double tracking is part of what makes that more frequent service possible.

None of this happens overnight and timelines for transit expansion projects tend to shift. Buyers should treat this as a reason for optimism about commute times improving over the years ahead, not as a guarantee of a specific new schedule by a specific date. Always check the current GO Transit schedule directly before making a decision based on train frequency.

What the commute means for buyers comparing Markham and Scarborough

Commute time is consistently one of the first few questions that decides whether a family buys in Markham or in a neighbourhood closer to downtown, like parts of Scarborough. On paper, Scarborough is physically closer to downtown Toronto and some Scarborough GO stations or the subway line can offer a shorter ride.

In practice, the gap is often smaller than people expect once you account for parking, local traffic to reach a station and the fact that many Markham GO stations have more parking capacity and less congestion right around the station itself. Families often choose Markham because the commute difference, maybe 10 or 15 minutes on an average day, is worth trading for a larger home, a newer build or a school they prefer.

The honest way to compare the two is to pick the exact station or route each household would actually use and time it during a normal weekday, both for the train and for driving. A generic comparison of “Markham versus Scarborough” is less useful than comparing the specific commute from the specific street a buyer is considering.

What to do next

• Check the current GO Transit schedule and fares for the Stouffville line directly on gotransit.com before assuming an old number still applies.
• Time your own likely commute at rush hour, both driving and by GO Train, before narrowing down a neighbourhood.
• Visit the specific GO station nearest any home you’re considering and check parking availability and walk time, not just distance on a map.
• Ask about planned transit upgrades near any property, since corridor improvements can affect both commute time and resale value over the years you own the home.
• Factor the full door-to-door time, not just the train ride, into how you compare Markham to other commuter suburbs.
