The Metric System vs. The Imperial System. Change?

Here in Canada, it's all over the map (government-wise) whether you enter D-M-YR or M-D-YR. It's because Brits say the 4th of January whereas we say Jan 4th... and some companies/agencies/govt depts still use the British way, following precedence.

But it’s different in Quebec, right?

It varies from province to province and agency to agency! Trickier for newcomers, though!
