Thank you for your response. Are there any instance where CBSA has denied entry of spouse (holding TRV)? I have marriage certificate to prove relationship.In short, yes, but you will both need proper quarantine plans on arrival. The usual caveats apply that decision is up to CBSA at border to admit your spouse under TRV as she arrives with (somewhat evident) plan to remain. Also documentation that she is your immediate family member (i.e. marriage certificates etc).
Should I ask my wife to travel independently to Canada (whenever they allow entry of visitors)? Once when she is in Canada, then I can apply for Spousal sponsorship.
