Canadian/Ontario Breeders?

I've been doing some digging and I only know of one person who breeds mice here in the north and naturally this makes obtaining one like finding a needle in a hay stack. I'm wondering if there are other mouse breeders around who are looking to re-home some of their little friends? I'm more than willing to answer questions about how my current mice are cared for and what their environment is like ect ect.

I'm just getting fed up with having to buy mice from the pet stores and finding out two days later that they have ringworm or god only knows what. It would be nice to have the assurance that I would be buying happy and healthy friends to look after.
