The only real thing you can do on your end is make a compilation of all messages and any communications sent to each other. It also helps if you have receipts and a paper trail of some sort.
If you have everything documented and in a neat pile/archived when it comes time to act you'll have everything you need.
Why did you wait a year? Honestly, I know be a good guy, benefit of the doubt and all but I would have waited 3 months, maybe 4 tops before threatening him with a call to the RCMP. Especially being international as it is...
