I'm not doubting it seems that way to you but in reality it looks a little different, numbers seem to vary where you look but a quick search shows there's something like 755 Mosques in Canada and 23000 churches.
A pretty similar story in the UK, 2122 Mosques and 38500 Churches
Its probably the same as when I buy a new car. I hardly see any of the model I'm buying until I've got one then everyone and their dog seems to have one
