Hi there!
I think the last Amiga dealers in Ontario finally died around 2002. That's when National Amiga in Ottawa disappeared, Oshawa Amiga closed and Randomize converted to Apple products. Softhut is probably your best chance, but they're damn expensive. And if you order from the US, watch out for Canada Customs - they'll rob you blind. Softhut did an exchange for me (already paid customs for the thing) and Canada Customs opened it up and charged me again!
I've driven through Belleville a few times. That's only about 100km from me. So technically I'm an "Amiga nut" and "in these parts". :-)
