Unfortunately American, but I really, really liked Vermont Chocolates' Skippers, always grabbed some when I drove to VT. Much higher quality than Mars M&M.
Hopefully some Canadian company can take their place.
I was checking the bags of Dare candies at my local Co-op. Nowhere on the bag does it say Made in Canada (or better yet Product of Canada). I suspect too many of the ingredients are internationally sourced so it doesn't meet the 51% cost threshold to have the Made in Canada label.
