The validity of a visa has nothing to do with status in Canada. There is no requirement to have a valid visa while in Canada. If there was, people with one-time entry visas would be illegal as soon as they got to Canada. CBSA determines status and length of stay upon entry.@canuck_in_uk
Even if the actual Supervisa is valid only till April 2020?? I thought it was the CBSA Officer’s mistake to not see the passport and visa expiry date and just stamp it for 2 years.
The officer did not make a mistake. Her status is valid until Feb 2021.
