2. Update your funds (again if she was not already part of your application
3. Inform Ontario about this change (to be safe also add officialy translated marriage certificate and new POF - if size of your family has changed). That is safe way to do.

But you can be sure, that once you get ITA, Federal will contact your province to recheck some data, so they shall be up to date when it comes to your current status.
