Canadians use a large mix of different units of measurement, from both the metric and imperial systems. This is regardless of if you are in Quebec or an English-speaking province. It is hard to know which ones to use if you are not a native of your province. Measurements of distance, lengths and areas are a good example to use here. The measurement system you use will depend on what you would like to measure: Size of a person: imperial Measurement in a building: imperial Size of a building: imperial or metric Distance and speed of cars: metric Size of an apartment: imperial Land area: imperial Land lengths: imperial Weight of a person: imperial Food weight: imperial or metric
