Well, even in my part of Canada, I can buy RO practically anywhere, hardware store, grocery store, heck even some corner stores. Normally it's about 15 bucks for an 18 lb bag. I recently found a local restaurant supply store that sells Maple Leaf for the same price. Even better my buddy found a place where I can get the Basques for less than 12 bucks. If I want to I can also get Kingsford Charwood(their lump) for about 15 bucks for the same size. My issue with either the Kingsford or the RO is that I don't know what wood is in there. I'm guessing by looking that it's mostly oak, hickory and ash. But depending on where it's made it could be whatever.
As for briquettes, for the odd time I need to use them, I'll use Maple Leaf, they're only ground charcoal with a wheat starch for a binder to hold the shape. Stuff like Kingsford or RO has charcoal, coal, ground limestone(so the ash has a pretty white colour) nitrites,....
