I've mentioned before that one goal I have as part of my Canadian born player collection is to get an autographed card of as many as possible.
I was recently helped on that with a Ryan Dempster card

I also received this Walker. It's a larger card but I won't turn down a Walker!
I did find a place that could help with a lot of the players I'm looking for, but I don't have the money right now. The Canadian Baseball Hall of Fame has balls, bats, cards, and other things autographed by inductees.
The cheapest card is inductee and current Phillies manager Rob Thomson for $10 CDN. The most expensive of the cards is Walker at $50 CDN.
