To go to Detroit, it is about 5 hours via Highway 401 and the Ambassador's Bridge in Windsor. There is a bridge in Sarnia, but I forget what it is called. For the Adirondacks and New England, you can use the Buffalo route, or go east to around Kingston and take I-81 from the 401 over the 1000-Islands bridge.
The US border line in Lake Ontario runs about 18 miles south of Toronto Airport.
No. Toronto is on the northern shore of Lake Ontario. The US-Canada border cuts across the lake.
The two cities border each other. Mississauga is Toronto's western suburb.
About 123 km / 76 miles.

Downtown Toronto is about 90 minutes by road from the US border crossings at Queenstown /Lewiston or at Niagara Falls. Of course, that presumes traffic is flowing freely, and at some times of the day that is very far from true.
Toronto is located in the country of Canada and in the province of Ontario near the Canadian and US border
Tijuana Airport adjoins the US border.
By car, less than an hour.
It really depends where you're going from in Toronto, but from Toronto to Niagara Falls is about 1 hour and 27 minutes (without the stop at the border)
a car ride
