My thinking and daily life are almost completely in metric.
Almost - except in the kitchen, our oven is an American model,(very common here) so in Fahrenheit and a lot of my recipes are cups, tsp Tbsp
Oh and I estimate the length of things by Hands (I have an 8" hand span) and yards (I learned a pretty accurate 1 yard pace years ago)
In a Canadian hardware store (and my workshop) you'll find a fairly equal mix of metric and "standard" hardware and tools.
