You'd think a straight shot across the border would be simple. It’s right there. You can practically smell the malt from the breweries in Buffalo and the lake air from the Toronto Harbourfront at the same time. But the actual distance from Buffalo New York to Toronto Canada is one of those things that looks tiny on a map and feels massive depending on when you leave your driveway.
Honestly, it’s a tale of two measurements: the physical mileage and the "border time." If you’re looking at a map, the distance is roughly 100 miles (160 kilometers). Give or take a few depending on if you're starting at Canalside or out by the airport. If you were a bird—a very fast one—you’d be there in twenty minutes. But you aren't a bird. You’re likely in a car, probably a Toyota or a Ford, staring at the taillights of a semi-truck on the QEW.
The physical reality of the drive
Let’s get the math out of the way. If you take the Peace Bridge—which most people do because it’s iconic and right there in the city—you’re looking at about 99 miles. If you go up to Lewiston and take the Queenston-Lewiston Bridge, you add a few miles, but you might save thirty minutes of sitting in neutral.
Driving this stretch is basically a tour of the "Golden Horseshoe." That’s the region wrapping around the western end of Lake Ontario. It’s one of the most densely populated areas in North America outside of the Northeast Corridor. Because of that, the distance from Buffalo New York to Toronto Canada is rarely about miles. It’s about the "Hogtown" crawl.
Traffic is the great equalizer. You can have a Ferrari, but you’ll still be doing 10 mph through Oakville at 5:00 PM on a Tuesday. I’ve seen people make this trip in 90 minutes. I’ve also seen it take four hours because a snowstorm blew off the lake or a fender-bender happened near Hamilton.
The Border Factor: The "X" Variable
The border is the wild card. There are four main crossings nearby:

- The Peace Bridge (Buffalo/Fort Erie)
- The Rainbow Bridge (Niagara Falls - mostly for tourists)
- The Whirlpool Rapids Bridge (NEXUS only)
- The Queenston-Lewiston Bridge
Each one changes your total travel time. The Peace Bridge is the most direct. You hop on the I-190, pay your toll, and boom—you’re in Fort Erie, Ontario. From there, it’s a straight shot on the Queen Elizabeth Way (QEW).
But wait. Check the Niagara Falls Bridge Commission website before you go. Seriously. If the Peace Bridge has a 45-minute delay for customs and Queenston-Lewiston has five minutes, drive the extra 20 minutes north. You’ll thank me when you’re grabbing a coffee in Burlington while the other guy is still stuck behind a tour bus in Fort Erie.
Beyond the Car: Trains, Buses, and Wings
Not everyone wants to drive. I get it. The QEW can be soul-crushing.
The Maple Leaf Train
Amtrak and VIA Rail run a joint service called the Maple Leaf. It’s a beautiful ride, honestly. You get to see the Niagara Gorge from a perspective you can't get from a car. The distance doesn't change, but the stress level does. Just keep in mind that the train has to stop for customs. Everyone gets off, everyone gets checked, everyone gets back on. It’s not "fast," but it is civilized.
The Bus Option
Megabus and Greyhound still run this route constantly. It’s cheap. It’s basic. It’s fine if you have a good podcast and don't mind the smell of stale pretzels.

Flying? Don't bother.
Technically, you can fly from Buffalo (BUF) to Toronto Pearson (YYZ) or Billy Bishop (YTZ), but you’ll almost certainly have a layover in Detroit or New York City. It’s ridiculous. You’d be flying 500 miles to cover a 100-mile gap. The only exception is if you have a private plane or use a regional charter service, but for 99% of us, that’s not happening.
What about the "Fast Ferry"?
Every ten years or so, someone tries to start a ferry service across Lake Ontario. It’s a lovely dream. Imagine sitting on a deck with a drink, skipping the Burlington Skyway entirely. The "Breeze" tried it in 2004. It failed. It turns out that maintaining a high-speed ferry in lake conditions is expensive and hard. For now, the water distance remains a barrier, not a shortcut.
The Hamilton Trap
If you are driving, you need to know about Hamilton. It’s almost exactly halfway. The QEW splits here. One way goes toward the Skyway bridge (the lake route), and the other (the 403) goes up the mountain toward Brantford.
Stick to the lake. But be warned: the Burlington Skyway is a bottleneck. If there’s high wind or an accident, the distance from Buffalo New York to Toronto Canada suddenly feels like a cross-country trek. If the Skyway is closed, you have to go through the city of Hamilton. It adds 20 minutes of stop-and-go lights. It’s the price you pay for the convenience of the border.
Regional nuances you’ll notice
The second you cross that line, things change.

- Speed signs: They switch from 65 mph to 100 km/h. Don't do 100 mph. You will go to jail. 100 km/h is about 62 mph. Most people do 115 or 120 km/h, but be careful.
- Gas prices: It’s sold in liters. It’s almost always more expensive in Ontario. Fill up in Buffalo or West Seneca before you hit the bridge.
- The Skyline: Buffalo has that amazing Art Deco City Hall. Toronto has the CN Tower. Both are visible from surprisingly far away on a clear day across the water.
Seasonal Realities
Winter is a different beast. Buffalo gets hammered by lake-effect snow. Toronto gets it too, but usually a bit less intensely because of the way the winds whip across the water.
If you’re traveling in January, double your time estimate. The distance from Buffalo New York to Toronto Canada might be 100 miles, but in a whiteout, 100 miles is an eternity. Black ice on the Garden City Skyway in St. Catharines is no joke.
Actionable Steps for your Trip
If you're planning this trek tomorrow or next week, don't just put it in Google Maps and hope for the best.
- Get a NEXUS card. If you do this drive more than twice a year, it’s the best $50 you’ll ever spend. It lets you skip the massive lines at the Whirlpool Bridge or dedicated lanes at the others.
- Download the Waze app. It’s much better than standard GPS for spotting "speed traps" (Ontario Provincial Police love the stretch between Grimsby and Oakville) and real-time accidents on the QEW.
- Check the Peace Bridge cameras. They have live feeds. Look at them before you leave Buffalo. If the truck line is backed up to the 190, go to Lewiston.
- Mind the "Arrival" time. If you arrive in Toronto at 8:30 AM, you will sit in traffic for an hour just to move five miles. Aim to hit the city limits either before 7:00 AM or after 10:00 AM. Same goes for the afternoon; avoid 3:30 PM to 6:30 PM like the plague.
- Roam like a local. Check your cell plan. Most US carriers include Canada now, but if yours doesn't, that 100-mile trip will cost you $100 in data roaming fees before you even see the Rogers Centre.
The journey is short, but it's dense. Treat it like a mini-road trip rather than a commute, and you'll find the transition from the Rust Belt charm of Buffalo to the glittering high-rises of Toronto is one of the most interesting short drives in North America.
