A Super Visa being valid for up to 5 (or in some cases up to 10) years doesn't mean the holder can stay in Canada continuously for that entire period — the date stamped by the border officer on entry is the actual limit for that particular stay.
What group members advised:- The stamped date is the deadline for that specific visit, not the overall visa validity. Your mother would need to either leave Canada by that date or apply for a Visitor Record extension before it, even though her Super Visa itself remains valid for years.
- The visa's multi-year validity just means she can re-enter Canada repeatedly over that period — each individual stay is still capped, commonly around 6 months (though the officer has discretion and can grant longer per visit, as shown by another member whose parents were allowed a 5-year continuous stay on entry).
- One workaround some visitors use for standard visas: crossing to the US by land and re-entering Canada resets a new stay period, though this specifically applies to regular visitor visas rather than Super Visas and may not be advisable without checking current rules.
Because border officers have discretion over the exact stay period granted at entry, and Super Visa rules differ from regular visitor visa rules, always check the exact date stamped in the passport or on the entry record, and confirm extension procedures with IRCC well before that date.
