Maple *anything* as a cultural *anything* is essentially Quebecois. There's a sliver of maple syrup production in far-eastern Ontario and a bit in Maine, but 90% of the world production is in la belle province. So there exists a Quebecois maple cartel as a result of this. If you have enjoyed real maple recently, you have done so with the blessing of the Cartel.
Anyway, maple-sugar candies? Yes, we do that. But by "we" I don't mean Canada to the west of Ottawa. I mean the parts where French is spoken. (And I don't know about the Maritime provinces, to be fair. Probably not those guys either.) Those candies are rather nice, though I rarely eat sugary things. They're less sweet than an equivalent hard-sugar candy, but still more sugary than I care for.
