I thought they don't include tax so they don't have to change it every time the tax rate change.

I suspect pricing of goods changes more often than sales tax rates.

Showing before tax prices (almost) makes sense in the US where every other street has it's own local tax rates. But Canada only has federal and provincial taxes so I suspect it's just to make the price look better - especially if you are comparison shopping with the US
