Saw this on neogaf. Looks like the publishers have been eager to push the price of games up here due to the low CDN$. Quick to revise when it is bad, slow when it is good.
Looks like PC for me now, games on steam are either the same in CDN$/USD$ or USD$ in CDN + 10%.
Best to just wait the month for games to drop in price now, as even the E3 sale will only drop them to $50-55
