The CZ 550 factory trigger I replaced was working fine until I broke the MIM part. I don't know about shipping to Canada, but would be willing to send the OP this unit. He could replace the broken part from his trigger. This one has a good pull with the set feature dialed out.

This may be an option if he gets no satisfaction from CZ. His trigger may just need some adjusting, but my offer stands.
