What words does Canada spell differently?

Canada has unique spelling patterns that often follow British English but sometimes American English, creating distinct Canadian spelling. Words that Canada spells differently from American English include those ending in our rather than or, such as colour instead of color, flavour instead of flavor, behaviour instead of behavior, and humour instead of humor. Words ending in re rather than er include centre instead of center, theatre instead of theater, and fibre instead of fiber. Canadian English typically uses grey rather than gray, though both are seen. Words with double l such as travelling instead of traveling and cancelled instead of canceled follow British style. Canada also retains British spellings like defence instead of defense and cheque for bank document versus check. However, Canada sometimes uses American spellings like tire rather than tyre and program rather than programme in many contexts. Canadian spelling reflects historical British influence combined with proximity to the United States, so it blends both, but official government and educational materials generally prefer British forms for words where a choice exists.
