CANADIAN, EH ?
You will notice that there are many differences in spelling of words in American English and British English. For example, the word color is American English and colour is British English. Also the word check is American spelling and cheque is British spelling.
In Canada, we typically use American spelling, however British spelling is also considered to be grammatically acceptable. Depending on the situation, you can set your spell check feature to American or British spelling. It is best to pick one spelling format and to use that, rather than switch back and forth between British and American spelling.
