Im going to hazard a guess that, with no elected political oversight of the classification system, the 'experts' at the RCMP lab will pee their pants and demand that no more scary black things be allowed into Canada.
Id bet it is deemed a variant. maybe that's cynical, but in this political climate (i.e. tidepod challenge politics) if it shares so much as a paint job with an AR Id guess they say restricted at best.
