Yes - earlier postings are correct in that it will take a bit of time for stock to move through from old priced inventory to the newer exchange rate reality.
However, having said that, other observations about Canadian distributors ripping off Canadian consumers also merit attention. It is very likely that we will NOT see much benefit from the stronger C$.
Very often, the distributors of film and other equipment in Canada are ONE or TWO companies (but usually one) and they play hard ball with your local retailer. The retailer is forced to source all (or most) of the distributor's product line from that distributor. The distributor is a virtual monopoly and behaves as such to maximize profits. The local retailer does his/her best to provide service, expertise, and such from their margins between their price to you and the high price paid to the distributors.
In the past, distributors could get away with it more, but with the advent of the internet and an efficient shipping system, Canadians have alternatives. But, unfortunately, the people in the end that lose are the retailers and their employees caught in the middle.
I try to support my local, full service retailer (the Camera Store) by purchasing consumables and the like from them. With our local support, they continue to stock traditional supplies for us, and although I pay a bit more, having a local source (and their expertise) is helpful.
As for equipment, well, I confess I usually buy used and the local retailer is really in that business as much. The local community purchases the retailer's ample stock of new camera gear and keeps the retailer going (as long as the general public does not get wise the games of the distributors).
Bottom line, the monopoly distributor model is the norm in Canada and only when they start to hurt will it change. Unfortunately, though, it will likely be the death of many good retailers along the way that will force any meaningful change.
Monopolized and abused in Canada...
