How far is Buffalo from Toronto Canada? What you need to know before you cross the border

If you’re sitting in a coffee shop in downtown Toronto looking out at the CN Tower, Buffalo feels like it’s just across the pond. Honestly, it kind of is. If you could drive a car straight across the surface of Lake Ontario, you’d be there in twenty minutes. But since most of us don't drive amphibious vehicles, the actual answer to how far is Buffalo from Toronto Canada depends entirely on whether you’re looking at a map or sitting in a three-mile backup at the Peace Bridge.

Distance is a funny thing in the Golden Horseshoe. On paper, Buffalo is about 100 miles (160 kilometers) away from Toronto. That’s a breezy drive in most parts of the world. In Southern Ontario? It’s a variable.

The raw numbers: Distance and drive times

Let’s get the technical stuff out of the way first. The driving distance between Toronto and Buffalo is approximately 158 kilometers if you’re taking the Queen Elizabeth Way (QEW). If you’re flying—which, let's be real, nobody does for this specific route unless they're on a connecting flight to everywhere else—the "as the crow flies" distance is only about 95 kilometers (59 miles).

You’re basically hugging the shoreline of Lake Ontario the whole time. You leave Toronto, swing through Mississauga, pass the Oakville Ford plant, hit Burlington, climb the Burlington Skyway (hold your breath if it’s windy), and then head through the Niagara region until you hit the border.

On a perfect day with zero traffic and a friendly border guard, you can do it in about 90 minutes.

But perfect days are rare.

Between the Gardiner Expressway construction—which feels like it’s been happening since the dawn of time—and the unpredictable madness of the QEW through Hamilton, you should probably budget two and a half hours. If there's a Bills game or a long weekend? Throw the schedule out the window. You’re living in your car now.

Why the border makes "how far" a trick question

When people ask how far is Buffalo from Toronto Canada, they aren't usually asking for the mileage. They want to know when they’ll actually arrive. The border is the great equalizer.

You have four main options to cross:

• The Lewiston-Queenston Bridge: Usually the best bet for people coming from Toronto who want to avoid the city traffic of Niagara Falls. It’s a massive bridge, plenty of lanes, and it drops you right near the outlets if you're looking to shop.
• The Rainbow Bridge: This is the tourist one. You get a great view of the Falls, but you also get the traffic of every person who decided to visit the Falls that day. It’s usually a mess on weekends.
• The Whirlpool Bridge: This is the "secret" one, but you need a NEXUS card. If you don't have one, don't even try.
• The Peace Bridge: This takes you directly into downtown Buffalo. It’s iconic, it’s windy, and it can have massive truck volume.

If you check the Niagara Falls Bridge Commission website before you leave, you might save yourself forty minutes of idling behind a tour bus. Seriously, check it. People forget that the "distance" isn't just the road; it's the 45-minute wait to tell an officer you didn't buy more than $200 worth of stuff.

Taking the bus or the train

Maybe you don't want to drive. I get it. Driving in Toronto is a special kind of stress.

The GO Train runs from Union Station to Niagara Falls, but it doesn't cross the border. You’d have to get off at the Niagara Falls GO station and then find a way across. It’s a bit of a trek.

Megabus and Greyhound (via FlixBus) are the real heroes here. They run pretty frequently from the Union Station Bus Terminal. It’s cheap. It’s easy. You can sleep. The only downside is that when the bus hits the border, everyone has to get off with their luggage, go through customs, and get back on. If one person has a complicated visa issue, the whole bus waits. I’ve seen a two-hour trip turn into a four-hour ordeal because someone forgot their PR card.

There is also the Amtrak Maple Leaf line. This is a cozy way to travel. It starts at Union Station and goes all the way to New York City, stopping in Buffalo along the way. It’s slow, though. It’s not about speed; it’s about looking at the vineyards through a big window while sipping a lukewarm coffee.

The "Shopping" factor and why we make the trip

Let’s be honest about why Torontonians are obsessed with the distance to Buffalo. It’s not usually for the architecture, though Buffalo has some incredible Frank Lloyd Wright houses and the Albright-Knox Art Gallery is world-class.

Most of the time, it’s Target. Or Trader Joe’s. Or the Walden Galleria.

Even with the exchange rate being what it is, there’s something about the American retail experience that draws Canadians across the border. When you calculate how far is Buffalo from Toronto Canada, you’re often calculating the cost of gas versus the savings on a pair of shoes.

Pro tip: If you're going for a day trip, remember your exemptions. If you’re there for less than 24 hours, you technically have zero personal exemption for bringing goods back tax-free. Most guards won't bug you over a bag of groceries, but if you've got a trunk full of electronics, be prepared to pay the duty.

What about the weather?

Snow. We have to talk about the snow.

Buffalo gets hit by lake-effect snow in a way that Toronto rarely does. Because of the way the wind blows across Lake Erie, Buffalo can get three feet of snow while Toronto just gets a light dusting and some gray clouds.

If you’re traveling in January or February, the distance between the two cities can feel like a thousand miles. A "whiteout" on the QEW near St. Catharines is no joke. Always check the weather in both cities before you head out. I’ve made the mistake of leaving a sunny Toronto morning only to hit a wall of white just past the Skyway. It’s terrifying.

Specific routes and shortcuts

Most people just GPS it and follow the blue line. But if you’ve done the drive a hundred times, you start to find "the ways."

Avoid the 403/QEW junction during rush hour if you can. If the QEW is backed up through Burlington, sometimes taking the 407 (the toll highway) is worth the $20 just to keep your sanity. It bypasses the worst of the GTA congestion and drops you back onto the QEW once things have calmed down.

Once you’re in the Niagara region, if the highway is a parking lot, you can take the "Service Roads." They run parallel to the QEW. You’ll hit stoplights, but at least you’re moving. You get to see some nice fruit stands, too.

Buffalo vs. Niagara Falls NY

Another thing: make sure you know where you’re actually going in Buffalo.

The city of Buffalo is south of Niagara Falls, New York. If you’re headed to the airport (BUF) to catch a cheap flight to Florida, that’s another 20 minutes past the border. The Buffalo Niagara International Airport is actually in Cheektowaga.

So, if you ask "how far is Buffalo," and you really mean "how far is the airport so I don't miss my flight to Orlando," add more time. A lot more.

Actionable insights for your trip

Don't just wing it. If you're planning to cross, here is the move:

1. Check the Bridges: Use the "Niagara Falls Bridges" app or website. If Lewiston has a 60-minute delay and the Peace Bridge has 5 minutes, drive the extra distance to the Peace Bridge. It's faster in the long run.
2. Gas Up in the States: Gas is almost always cheaper in Buffalo. Even with the conversion, you'll save money filling up before you head back to Canada.
3. Roaming Data: Check your phone plan. Most Canadian carriers have "Roam Like Home" features, but they charge you $12–$15 the second you ping a tower in Buffalo. If you do this often, get a US SIM or a cross-border plan.
4. The "Hidden" Buffer: Always add 45 minutes to whatever Google Maps tells you. Between the 401/Gardiner merge and the border line, the "estimated time of arrival" is a lie.
5. Duty-Free: If you’re looking for booze or perfume, the duty-free shops are at the bridges. But remember, if you’re only there for a few hours, you might have to pay tax on those "deals" when you hit the Canadian side.

The distance between Toronto and Buffalo is short enough for a lunch date but long enough to feel like a real getaway. Just respect the QEW, keep your passport handy, and maybe bring a snack for the border line.
