Toronto started as York, a small British garrison town founded in 1793, and was renamed Toronto in 1834. Today it is Canada's largest city, with about 2.8 million people inside the city limits and more than 6 million in the wider region, and more than 160 languages spoken. Indigenous peoples lived on this shore for thousands of years before the British arrived, and the city's modern character comes from the waves of immigrants who came after: Irish in the 1840s, then Italians, Jews, Chinese, Portuguese, Greeks, Caribbean and Korean communities, and many more.
That is the reason to come, more than any single landmark. Toronto doesn't have one old center that tells the whole story. It has a tower, a lakefront, a castle built by a financier who went broke, two big museums, and then the neighborhoods that are the real city: Koreatown on Bloor, the Chinatown on Spadina, Kensington Market, Greektown on the Danforth, Little Italy on College and Little India on Gerrard, each with its own streets of restaurants and shops. Five days is the right length. It lets you do the big sights without rushing, spend a full day in Kensington Market, Chinatown and Queen West, and still keep one day for Niagara Falls, about two hours away.
The plan runs by geography. Day one is the market, Union Station, the CN Tower and Harbourfront, day two the ROM, Koreatown and Casa Loma with a hockey or basketball game at night, day three Kensington Market, Chinatown, the Art Gallery of Ontario and Queen Street West, day four the Toronto Islands, the Distillery District and Greektown, and day five is Niagara Falls. Algonquin Park, Prince Edward County and Ottawa are in the extras; if you are going on to Quebec, our Montreal guide picks up where this one ends. More on the country in our Canada guide. Start on a Wednesday. The Royal Ontario Museum, the Art Gallery of Ontario and St. Lawrence Market South are all closed on Mondays, the GO train to Niagara runs best on weekends, and a Wednesday start lands the museums on Thursday and Friday and Niagara on Sunday.
