In Canada, check out Princess Auto (better than Harbor Freight). They have plenty of surplus stuff, not necessarily military though. CanadianPrepardness.com and Stephenson's are also two good sites for stuff.

Boreal Mountain Anoraks (BMA) are in your own backyard of Montreal - they make fantastic wool products but their website is in $US. https://borealmountainanoraks.com/product/bmas-100-loden-wool-blanket/
