Walkman eats my tapes. Where can I find parts for it in GTA, Canada?

So, I have a Sanyo MGR-66 walkman, that constantly eats my tapes. I can tell that the belt definitely needs replacing because it always gets stuck on forward and rewind and it sounds a bit slow. Yes, I have tried using a rubber band, and it technically works, but it sounds really bad.

I've tried ordering a new rubber belt on eBay, but there's only 1 person selling the belt for my model, and the shipping time is very very long. So, I was wondering, does anybody know if there is a physical store somewhere in the Greater Toronto Area in Canada that might sell a belt for my walkman or perhaps would be able to fix it themselves?

Also, is there any other reason that my walkman may be eating tapes?
