The Canadian city closest to Niagara Falls is, fittingly, Niagara Falls, Ontario. It is located directly across the Niagara River from its American namesake in New York, and it is the city that directly overlooks the most powerful section of the falls—the Horseshoe Falls. Unlike the American side, which is largely a state park, the Canadian city is a major tourist hub known for its high-rise hotels, the Clifton Hill "Street of Fun," and world-class casinos. If you are looking for the nearest major metropolitan city, Hamilton, Ontario is about 64 km (40 miles) away, while Toronto is approximately 67 km (42 miles) to the north. While many visitors fly into Toronto Pearson International Airport (YYZ), the city of Niagara Falls, Ontario is where you find the best panoramic views and the famous "Maid of the Mist" (known on the Canadian side as Niagara City Cruises). In 2026, the city remains the primary destination for travelers who want to be within walking distance of the thundering water and the vibrant nightlife of the Niagara region.
