Being a Canuk myself, and growing up on the farm, I was exposed to both systems. My father talked in acres and miles [ still does] and really it makes sense as they land was marked out in the same sections as any other farm land[1 mile by 1 mile]. One trick I figured out to help me follow directions was to use a speedometer to convert like a slide rule. If someone says go 4 miles north and 3 miles west, if you look on the speedo, 40 miles/hr is about 60km/hr so 4 miles is ~ 6km's. I used to navigate all over the place using this to 'convert' the directions into something usable/definable by the vehicles odometer. There are nice things about the metric system however they did complicate it more than needed. If you never use cm, cL you'll be fine. [instead only use mm and mL or meters and litres]
Someone mentioned that a cc isn't a ml, care to explain? I've never heard this.
One thing I've always wondered about is, did the metric people figure out a way to navigate the globe? [ie Lat/Long]
