Thanks to everyone for the input.  Canadian Geographic magazine was asking if we (at the museum)  knew of taxa that were native to Canada (or more broadly, North America) that had been introduced elsewhere.  I still think there is great asymmetry.  In Bousquet et al. checklist of Canadian beetles I counted 77 Curculionidae alone that are established in Canada from European origins.  For all Coleoptera there are 8237 species in Canada and 628 introduced (adventive) (Bousquet et al. 2013).
