I am with Mcgrath on this. Canada adopted the metric system, to the continuing confusion of anyone not brought up in the system.
Stores here in Calgary conveniently have scales that weigh by the pound, so I know how much I am getting when I buy fruits, etc. sold in bulk.
I can look across the countryside from an elevation, and know how roughly how far away an object is in fractions of a mile. I have no mental image of the distance in metric measurement.

In research work during my working career, I used both systems, and some not mentioned here, using handy-dandy conversions, but I did not have to take both home with me.

Like the U.S., Canada was surveyed in the English system, so all land boundaries are in English whole numbers; when metric is applied, fractional measurements appear. My home lot is 75 feet wide; this is 23.416666 meters (metres). [I think- I may be using my pocket calculator incorrectly].
