I tend to fail to see the benefit. Over the last few years, Canada has dropped it's old colonial-style based air regulations in favor of increased harmonization with the US FAR's. The US FAR's are not the greatest, however, given the close ties to the US geographically, economically, politically, etc., it only makes sense to link to the closest powerhouse . . . in the same way that many countries in the Eastern Hemisphere are linking themselves to JAR OPS. Pragmatism more than anything.
