Maps elsewhere (2)
All are worth a look. Here is a regional map of where it is more (or less) accepted to smoke in a house.
There is a sharp regional difference between south-central Ontario and Quebec, with the upper Ottawa Valley more tolerant. In the West, an area of the prairies in southern Saskatchewan and Manitoba west of Brandon stands out, while in the Maritimes Cape Breton and an area in northern New Brunswick more people smoke in their houses.
