If you’re driving toward the border between New York and Ontario, you’ll eventually hit a stretch of road that feels like it’s hovering over the water. That’s the Thousand Island Bridge Canada connection. Honestly, calling it a "bridge" is a bit of an understatement because it’s actually a massive system of five different spans. People get confused. They think they’re just crossing one river, but you’re actually hopping across a series of islands like a stone skipping across the St. Lawrence River.
It’s beautiful. It’s also a bit terrifying if you hate heights.
The whole thing started back in 1937. It only took about sixteen months to build, which is wild when you think about the engineering involved in the 1930s. President Franklin D. Roosevelt and Prime Minister Mackenzie King actually showed up to open it in 1938. They stood there, probably sweating in wool suits, celebrating what they called a "peace bridge." Since then, millions of people have used this crossing to get from Ivy Lea, Ontario, to Collins Landing, New York.
But there’s a lot more to it than just a toll booth and a nice view.
The Weird Geography of the Thousand Island Bridge Canada
Most travelers don't realize they are crossing multiple bridges. When you're heading north from the U.S., you hit a suspension bridge first. Then you’re on Wellesley Island. You drive for a bit, pass through a massive park, and then—boom—another bridge. This one is an international rift bridge. It’s actually one of the shortest international crossings in the world.
There’s a local legend—mostly a joke for tourists—that a tiny footbridge on Zavikon Island is the shortest international bridge in the world. It’s not. Both sides of that tiny bridge are actually in Canada. But the real Thousand Island Bridge Canada system is where the actual border logistics happen.
The Canadian side specifically lands you right in the heart of the Frontenac Arch Biosphere. This isn't just a road; it’s a UNESCO-recognized ecological crossroads. The rock you see sticking out of the water? That’s billion-year-old granite. It connects the Canadian Shield to the Adirondack Mountains. Most people just see it as a "nice view," but geologically, it’s one of the most important corridors in North America.

Tolls, Cash, and the "E-ZPass" Struggle
Let's talk money because that's what everyone asks about. As of 2026, the Thousand Islands Bridge Authority (TIBA) has modernized a bit, but it can still be a headache if you aren't prepared.
- You can use E-ZPass. This is the easiest way. If you have a tag from New York or any other participating state, just roll through.
- Credit cards are fine. They took a long time to get there, but they’re standard now.
- Cash is tricky. They accept both USD and CAD, but don't expect a great exchange rate at the booth. They set their own rates, and they usually favor the house.
- Pedestrians and Bikes. Yes, you can actually walk across. There’s a sidewalk. It’s narrow. It’s windy. But the photos you can get from the top of the Canadian span are unbeatable.
The height of the Canadian span is about 150 feet above the water. When a Great Lakes freighter passes underneath, it looks like a toy boat. If you’re walking, the vibration of the transport trucks passing you at 80 km/h is... an experience. You’ll feel it in your teeth.
Why the Ivy Lea Side is Better for Locals
Once you cross the Thousand Island Bridge Canada into Ontario, you’re in Ivy Lea. If you just keep driving toward Highway 401, you’re missing the point. The area right under the bridge is home to some of the best scuba diving in the world. I'm not kidding. The St. Lawrence is famous for shipwrecks because the current is fast and the islands are everywhere.
The A.E. Vickery is a popular wreck right near the bridge. It’s a wooden schooner that sank in 1889. Divers go down there specifically because the water is surprisingly clear, though the current can be a nightmare.
If you aren't into getting wet, the 1000 Islands Parkway is right there. It’s a slower, two-lane road that runs parallel to the 401. Take it. It follows the shoreline and gives you access to small towns like Rockport and Gananoque. In Rockport, you can see "Islandview" houses that make you wonder how anyone affords the taxes, let alone the boat gas.
Border Crossing Realities
The Thousand Islands border crossing (Lansdowne on the Canadian side) is usually faster than the Lewiston-Queenston or the Peace Bridge in Buffalo. Usually.

On a holiday weekend? Forget it. You’ll be sitting there for two hours watching the temperature gauge on your car. The CBSA (Canada Border Services Agency) officers here have seen everything. They are professional, but they don't have a huge sense of humor about "forgetting" you have a trunk full of cheap wine or a handgun you forgot was in the glove box.
Pro tip: Check the "Border Wait Times" app before you commit to this route. If Lansdowne is backed up, sometimes the Ogdensburg-Prescott bridge further east is empty. It’ll add 30 minutes to your drive but save you an hour of idling.
The Engineering Marvel Nobody Mentions
We talk about the bridge like it’s one solid object. It’s actually a mix of suspension, Warren truss, and masonry. The Canadian span is a suspension bridge, which is why it has those iconic towers you see in all the postcards.
The Thousand Islands Bridge Authority is a weird entity. It’s a "bi-national" body. It was created by the New York State Legislature, but it operates in both countries. This is rare. Most bridges are owned by one side or have two separate agencies that bicker over maintenance. Here, it’s one group. They manage the maintenance, the tolls, and even the Boldt Yacht House on Wellesley Island.
Maintenance is a constant battle. The salt from Canadian winters eats the steel. The humidity from the river causes corrosion. They are basically painting or repairing the bridge 365 days a year. If you see a crew hanging off the side in January, say a prayer for them. It’s brutal work.
Misconceptions About the Thousand Islands
People think there are exactly 1,000 islands.
There are 1,864.
To be counted as an island, it has to stay above water 365 days a year and support at least one living tree. Some of them are just big rocks with a very determined pine tree sticking out.

The Thousand Island Bridge Canada gives you the best aerial view of this. When you're at the apex of the Canadian span, look west. You’ll see the "Admiralty Group" of islands. It looks like a jigsaw puzzle that someone gave up on.
Staying Safe and Avoiding Fines
The speed limit drops significantly as you approach the bridge. On the Canadian side, the OPP (Ontario Provincial Police) love to sit just past the bridge on the Parkway or the 401 on-ramps. They know people are excited to be "free" of the border and tend to heavy-foot the gas.
Also, watch for deer. Wellesley Island is basically a giant deer sanctuary. They don't understand international borders, and they will jump in front of your car without a second thought.
Actionable Insights for Your Trip
If you're planning to cross the Thousand Island Bridge Canada, do these three things to make it suck less:
- Check the Wind Forecast. If the winds are over 60 km/h, they sometimes restrict high-profile vehicles (RVs and trailers). If you're towing a boat, the sway on the suspension span can be terrifying in a gale.
- Download Your Maps. Cell service is notoriously spotty right at the rift. Your GPS might freak out and think you’re in the middle of the river. Download the offline map for the "Leeds and Grenville" area before you leave home.
- Stop at the Duty-Free... but maybe not. The Duty-Free on the Canadian side is great for spirits, but check the prices on the US side first. Sometimes the "deals" aren't actually deals once you factor in the exchange rate.
- Visit Skywood Trek. If you have kids and you’ve just crossed into Canada, there’s an aerial park right near the bridge. It lets them burn off "car energy" by climbing through the trees.
The Thousand Island Bridge Canada is more than just a piece of infrastructure. It’s the gateway to a very specific kind of summer lifestyle. It’s about boats, granite, and the smell of fresh water. Whether you're a trucker hauling freight or a tourist looking for Boldt Castle, that drive over the spans is the moment your trip actually begins.
Pack your passport, keep your eyes on the road (not just the view), and maybe keep a few loonies in the cup holder just in case the card reader is acting up. It happens.
To make the most of your arrival, head toward the 1000 Islands Parkway immediately after clearing customs. Follow the signs for "Scenic Route" rather than the 401. This path takes you through the heart of the river communities, offering immediate access to boat tours and local diners that the highway completely bypasses. If you’re towing a trailer, use the Lansdowne scales if required, but otherwise, stay in the right lane and enjoy the descent into the valley.
