If you get married, your will is cancelled (except in Quebec).

Question

Quizplus · Accepted Answer

In Canada, getting married automatically cancels any previous wills that you may have made, with the exception of Quebec. In Quebec, marriage does not cancel a will but it does limit the ability of the surviving spouse to inherit unless there is a valid will in place. It is recommended to update your will after getting married to ensure that your wishes are properly reflected.
