Canada really stifled its non-car mobility when it basically cut all intercity rail service after WWII though, especially for the interior and west coast. We used to have a pretty good train network for getting between nearby cities like Calgary and Edmonton, Calgary and Vancouver, Kelowna and Vancouver, and even Victoria and Nanimo. We don't even have a proper Vancouver to Abbotsford commuter rail despite them being right next to each other. There were obviously even longer routes like Toronto to Vancouver but that can't really compete with planes so no real surprise they went (I don't count that one Via Rail tourist service as a proper Vancouver-Toronto line). Pretty much the only remaining part of Canada with decent intercity rail is on the Toronto Ottawa Montreal corridor, and it does get decent ridership because of it.

Also, within many Canadian metro areas, which if you live in one you'll most likely stay inside of it for the vast majority of your daily travels, you could actually reasonably live without a car depending on where exactly you live and what you have to do. I for one live in the Vancouver area and don't own a car. I take the bus and metro almost everywhere, and on the rare occasion I need to go somewhere that's straight up without public transit access I just take an Uber or something. I think the fact that many of the largest Canadian cities are investing now more than ever in building more public transit, and those projects are more often than not praised by residents with high ridership to back it up is a sign that there is a high demand for non-car travel at least within urban areas. And even for smaller towns, the infrastructure is already there for good bus services like most small towns in Europe have, and if we want to go beyond that and upgrade particularly high demand routes, streetcars and tram-trains are also tried and true options for lower density urban areas. Canada even had plenty of streetcars before we decided to rip them up.

I get that this doesn't really help people in rural or remote Canada but if we can work to reduce the need for cars in a city, where the majority of people live, that's still a win and sets a precedent for future transit expansion into lower density areas. Non-car dependency isn't an all or nothing deal for the entire country.

Obviously there are many challenges to Canadians finding car free alternatives. If you're in a situation where you do need to own a car, then you need to own a car, and you shouldn't feel bad for that. But I think that simply saying that there is no other way in Canada or that we're just hopeless and doomed to car dependency forever due to our population density is missing a lot.

I will also recommend the YouTube channel RMTransit for really good Canadian public transit content.
