Metric System in Canada

do they really sell metric air? no wonder my tires were under inflated.

Yes, and thank God you're not in England or they would make you put it in from the wrong side of the tire.

Yes they do. Be aware they sell it by the liter instead of the quart. Fortunately with the exchange rate favorable to the dollar, you get more for your money. Be careful when you get into the capital city areas. Just like America, there is mostly hot air being pushed off on the citizens.

Yes, and be sure the place you stop has already changed over to summer air, some unscrupulous places will try to pawn off their leftover winter air on tourists.

This of course will throw off your ‘cold’ air pressures.
