@tpuiwy Most of the francophone (french-speaking) areas in Canada are in the province of Quebec.
There are some places in Ontario where French is spoken, but it's far less common than in Quebec.
In Toronto, only about 1% of the population speaks French as their native language. There are in fact more native Spanish speakers than native French speakers in Toronto.

The closest thing to a francophone city in Ontario is Ottawa.
Roughly 15% of Ottawa residents are native French speakers and the city borders Gatineau (a francophone city in Quebec). Ottawa is still mostly English speaking though and depending on where you live, your exposure to French may be limited.
It's worth noting that Ottawa is the political capital of Canada where most of the federal government and parliament buildings are located. Canada has a bilingual federal government and parliament, so if you watch government/parliamentary proceedings you will often see them switch back-and-forth between English and French.
Note: Ottawa gets a little colder than Toronto in the winter. Whereas Toronto usually ranges from -20°C to 10°C in the winter, Ottawa usually ranges from -30°C to 0°C.

There are some smaller towns in Ontario that are majority francophone, but most of these towns have a population under 15,000 people with the exception of Clarence-Rockland which has a population of 23,000.
Sudbury is another alternative to consider. After Ottawa, it's the next largest city in Ontario with a sizeable francophone population.
However, Sudbury is still a majority anglophone (English speaking) city and it only has a population of 160,000 (so it's much smaller than Ottawa). Sudbury is also located in a relatively remote area (around 5 hours north of Toronto), so it's not an ideal location.
