I don't see too many MLB team merch in the streets. Maybe because I'm not a big baseball fan so I don't pay attention to it. But from the ones I did notice, it was mostly Jays merch. In fact, I think I haven't yet seen someone wear Mariners merch in BC. I guess most people here still have the Canadian identity and would support the Jays over the Mariners even though the Mariners are so close.

Many many Canucks fans though, but I guess that's obvious haha.
