To all Canadians, British, Australian, South African etc

pretty sure they all use the ou's there

I believe I have been using the mix between Canadian and U.S. ... But it's mostly Canadian :) -I have always used -our such as colour and behaviour. -Used the word Centre as a place. For Instance, Medicare Centre. -Center as a middle point of a geometry, object or a place. -Defence/Defense -Gray/Grey -Fulfill/Fulfil I was accustomed to using the Canadian way when I was growing up. However, I have been told that they were both correct and didn't really understand why it was such a case. I figured it was just a different way to spell and did not give much attention to it. Maybe there was a simultaneous exposure in using both through my life. For example, Canadian School teaches and uses Canadian way to spell a word. Some novels were from U.S. which also exposes some of U.S. way of spelling at the same time. Internet I believe was mostly U.S.? way of spelling. Those factors have gotten me a mix up in the past. https://media1.tenor.com/images/ba98eb464bff48236b933b404c8035ee/tenor.gif?itemid=5472206
