Just taking a really quick look at Canadian Dollars compared to US Dollars, the exchange rates to me would indicate part of the problem.
Oh, agreed that's definitely part of the issue, but exchange rate alone can't be responsible for variances like (to use one example) Sand and Stars, where it's $0.99 in the US, and $29.99 in Canada.
We have always paid more than the US for most products, even after exchange is taken into account. We were still paying more for items back when our dollar was worth 10 cents more than theirs. It was something the media liked to go on and on about back at the time.
