The only three things I hear referred to in inches are height, woodworking, and paper sizes. Everything else tends to be metric. (23, lived in BC/AB/SK/MB/PQ/NB, your experiences may vary.)
Also on the cooking theme, oven temperatures are measured in Fahrenheit and recipe quantities are measured in cups, teaspoons and tablespoons.
For weather, summer temperatures are generally measured in Fahrenheit (because it's just not that impressive to say, "Man, it's 40 degrees out!") but winter temperatures are generally measured in Celsius (because it is impressive to say, "Man, it's minus 20 out!").
Other areas, like home construction, are still exclusively imperial. We use 8 foot 2-by-4 boards, not 2.4 m 5cm-by-10cm boards.
