The dollar amount in CAD was normally higher than the equivalent in USD. For example, next to the bar code on the back of a paperback, it would list the prices as $15 USD or $20 CAD. Many other goods have similar price differences.

Lately in the US it seems like a lot of prices are increasing to the same number value, despite the exchange rate.

I'm 42, so, ah, no.

What I mean is that basically since forever things were cheaper in the US than in Canada.

Gas? 25%-50% cheaper. Cheese (of course) 50% cheaper. Electronics, cars, clothes, hotels, beer, food at restaurants, etc. etc.

Now, everything is more expensive in the US than Canada.
