How early should I leave Markham to get to Pearson Airport on time?

How long is the drive from Markham to Pearson?

Plan on 40 to 55 minutes door-to-door from Markham to Pearson in normal conditions — the distance is roughly 40 to 45 km. The fastest route is the 407 ETR westbound to Highway 427 South into the airport, which holds up even at peak times.

The 401 is the trap. In weekday rush hour, the 404-to-401-westbound cross-town crawl can stretch the same trip to 75 to 90 minutes. East-to-west across the top of the GTA is the region's single worst rush-hour axis, so the route you pick matters more here than almost anywhere else.

Off-peak (mid-morning, evenings, weekends) the 407 run can be as quick as 35 minutes. But you should never plan to the best case — build to the realistic case and keep a cushion.

• 407 ETR → Hwy 427 South: ~35–45 min, most reliable (tolled)
• 404 → 401 westbound: 45 min off-peak, 75–90 min in rush hour
• Distance: ~40–45 km from central Markham/Unionville
• Reliability: the 407 avoids the 401's daily congestion almost entirely

So what time should I leave home?

Work backwards from your flight, not just the drive. Airlines advise arriving 2 hours before a domestic flight and 3 hours before an international one, and Pearson echoes that. Add your 40-to-55-minute Markham drive on top.

A simple rule for Markham travellers:

• Domestic flight: leave home ~3 hours before departure (2h at airport + ~1h drive/buffer)
• US or international flight: leave home ~3.5 to 4 hours before departure
• Weekday AM rush (6:30–9:30) or PM rush (3:30–6:30): add 20–40 minutes
• Winter storm, long-weekend Friday, or March break: add another 30+ minutes
• Checked bags or first time at a new terminal: lean to the earlier end

407 ETR vs the 401 — is the toll worth it?

For an on-time airport run from Markham, the 407 is almost always worth it. It converts an unpredictable 401 gamble into a dependable 35-to-45-minute drive, which is exactly what you want when a flight is on the line.

The catch is the toll — the 407 ETR is a distance-based private toll road, and a cross-GTA airport trip is one of its pricier segments, especially in peak hours when per-kilometre rates are highest. Video-tolling (no transponder) adds a camera charge and a per-trip fee on top.

This is where a chauffeured car quietly wins: with Toronto Airport Limo the toll is already inside your flat, upfront quote. The chauffeur takes the fast toll route as a matter of course, and you never see a surprise 407 bill weeks later.

• 407 ETR: fastest and most reliable, but tolled (peak rates are steepest)
• 401: toll-free but congested and unpredictable westbound in rush hour
• In a flat limo quote, the toll is absorbed — no separate charge to you
• Chauffeurs default to the reliable route so you make your flight

How a chauffeur removes the timing guesswork

A car service takes the two hardest variables off your plate: route choice and departure timing. Your chauffeur watches live traffic, picks the 407 when it pays off, and builds in the right buffer for your terminal and flight — so you are not doing GTA rush-hour math at 5 a.m.

For arrivals back into Markham, Toronto Airport Limo tracks your flight live, adjusts pickup for early or delayed landings, and meets you inside the terminal at baggage claim. No parking, no cross-town self-driving, no watching the 407 toll meter.
