We're told that Canon Canada will soon be increasing the prices of lenses by around 20% around the end of March or early April. Americans in the know have been buying up Canadian lenses for quite some time, as the weak currency and the fact Canon Canada doesn't have MAP pricing on lenses made for some good discounts for American shoppers.
We haven't had this confirmed from Canon Canada, but it shouldn't come as any sort of surprise to consumers on both sides of the border.
While the Canon EOS-1D X Mark II is launching in the USA at $5999, in Canada it's launching at $7999. There is some CPS Canada member relief though, as you should be able to get the camera body for about $6800 CAD.
