Canada's monarch butterfly population has declined sharply over recent decades, with overwintering colonies in Mexico shrinking by more than 80% since the 1990s — a collapse driven by milkweed loss along migratory corridors through the continental interior. The Royal Canadian Mint has issued naturalist-themed circulation dollars sporadically since the loon's introduction in 1987, but wildlife subject dollars of this kind typically see limited actual circulation, absorbed immediately by collectors and tourism channels.
