I live in Canada, and I’d say there is a lot of thong wearing in Toronto and Vancouver.
Toronto
Toronto is the largest and the most multi-cultural city in Canada. There is a huge Latin American and Caribbean population in Toronto and I believe that thong wearing is very much prevalent in these communities.
We all know that Latinas are avid thong wearers and this is also true in Toronto. Whenever I go to a beach in Toronto, I see many Latinas in thong swimsuits. They’re usually the ones that wear the skimpiest thongs on the beach.
I don’t know much about Caribbean culture, but every year, there is a big Caribbean festival in Toronto. I’ve seen photos of this event, and let me tell you, a lot of people come to the parade with very little clothing on.
These are online photos of the Toronto Caribana. As you can see, there are quite a few people in thongs, and my guess is you won’t find this much thong wearing at any other cultural event.
Vancouver
People in Vancouver are very laid back. This is where Lululemon started business, and you see a lot of women in leggings and yoga pants. Obviously, those who wear tight leggings and yoga pants are likely to wear thongs to hide panty-lines. On the beach, there are a lot of women in cheeky style swimsuits. Cheekies are the norm on the beaches of Vancouver.
