Ok after many hours of search here's what I found
Based on the following website, the Weston #8 is a good grinder for grinding chicken bones!

If you really want to buy from a Canadian store, here is the only place I found:

Tasin TS-108 is one of the most popular meat grinder in the Barf and Raw feeders community. It is impossible to get one FROM Canada, but if you buy it directly from the following website
http://www.onestopjerkyshop.com/tasi...eat-grinder-1/
they charge 64$ for shipping. Then, if you use that little tool to figure out the REAL cost after tax, import and everything:

you will probably find out that total cost is about 250CAN$... which is not THAT bad for a 1200Watts grinder!
