Ontario is a big place. Are you near a major city? some of the larger cities have co-ops. Perhaps you might do well volunteering at a co-op and then see if that's what you like?

I go to the Buffalo co-op and IIRC the head mechanic there started as journeyman and travelled a bit to find work. It might be a door into something permanent as the bike community is a small community and you might hear of an opportunity there that you wouldn't normally hear of. If you can only get bike work part time, you could always feed yourself with the automotive job as you build that reputation. I know of a Canadian frame builder who "has another job" because there isn't a lot of folks here looking to have a frame custom built. I do see ads on Kijiji offering tune-ups and repairs and you might build a rep that way as well.
