Welcome to the Spooky Season, Canadian Newcomers! If this is your first October in Canada, you might be wondering why your neighbours are decorating their homes with skulls, ghosts and giant spider webs. This is for one of Canada’s favourite holidays: Halloween, celebrated on October 31st every year. And what does “Spooky” mean? It is a playful slang word for “scary” which suggests that it really is not scary at all.
