Of all the things I read on the internet today, this might be the most mind blowing one - you lived there for 10 years and don't know a single person with a car in Toronto?
I lived in Toronto for 14 years, sold the car I arrived with after two years, and bought a car a couple years before the pandemic after we moved into a less central, but still urban, neighbourhood. Neither car had dedicated parking, we had a street parking permit which meant I could usually park within a block of home.
I did know people with cars, but I knew a lot more people without.
The main reason we bought a car in 2018 was that Car2Go, which offered one-way car share trips in Smart cars, pulled out of the city.
On the other hand, if you live in the suburbs, you virtually have to have a car. The 401 at rush hour is filled with people coming in and out of the city core.
