Still has to be in metric here.

Aren't you glad that modern tires are sized using one metric measurement (the tread width), one imperial measurement (the wheel diameter), and one unitless quantity (the aspect ratio)? Otherwise, you'd have to change the tires when you change the air; putting metric air in inch tires would cause all sorts of problems.

Aspect ratio is not unitless its just that a ratio. its the sidewall height based on a percentage of the tires width.

and minimum wage here in Ontario is roughly $427/h

Yes, and each of them is paid at least the minimum wage.

Do not rely on your cheap PSI tire pressure gauge when you cross into Canada. You will need to get one of our kilopascal gauges to be sure.

Metric air is actually sold by the English Pound

Don't waste your money on metric air. Spend a little more and get the good stuff, Metric Nitrogen.

Yes, the air is metric here! The only countries in the world that don't have metric air are Myanmar, Liberia and the USA!
