Keep Life Random
Who said you can't say 'Merry Christmas' in Canada? Now, whether or not you'd want to is different... if I had a business I wouldn't be putting 'Merry Christmas' anywhere near it. But I could. This post is dumb in all possible ways. Whether or not people are saying 'Merry Christmas' has nothing to do with multiculturalism.
The question is why wouldn't you put "Merry Christmas" anywhere near your business. It may not have anything to do with multiculturalism policy, but the multiculturalism ideology that you cater to a diverse "non-Christmas" celebrating market and consumer base, is probably the reason. Multiculturalism operates on numerous levels, so to argue that it has nothing to do with saying "Merry Christmas" is like saying racism doesn't exist in Canada. It may not exist in your everyday life, but it still exists.
