Yes you would need to submit a webform indicating your change in marital status as soon as you got married as the name of your spouse and their status in Canada because otherwise you would be misrepresentation. Before spouses were more easily able to get TRVs it would be a big deal and getting a TRV was much more difficult. Is your spouse working? Do they have an international travel history especially to countries like US, UK, Australia, etc.? Do they have savings? Another good option would be to apply for the TRV once you are married.
