Literally in your comment you say you want American English spelling. Which Canadian English is not. Every point I made was directly in response to what you wrote.
English orthography does not have a binary distinction from one dialect to another. It is absurd to talk about them in such a binary manner.
Nothing weird about https://en.wikipedia.org/wiki/Oxford_spelling
Canadians themselves are also pretty inconsistent personally and often use American spellings, especially outside of the -our/-or and -re/-er series, which are the most well-known differences. Part of this is probably attribuable to the fact that Canadian media used American spellings until the 90s.
Canadians also may be found using hyperbritish forms proscribed by the OED, such as "honourary" for "honorary" and so on.
