What’s going on with IShowSpeed and Canada?

I’ve seen people say IShowSpeed used to avoid Canada or Toronto, and I remember him saying something about his grandfather/family history, but I’m not sure if he was being serious or joking.
Now he’s apparently going to Toronto for a Portugal World Cup game because of Ronaldo, but he still seems kind of uninterested in Canada itself.
What’s the actual context here? Is there a real reason, or is this just a stream joke people exaggerated?
