Length of admissions
An officer at the POE will determine the length of time that a temporary resident may remain in Canada.
Note: In general, stamps issued by CBSA officers at the POE are valid for a period of 6 months from the date of entry.
If a handwritten date has been placed under the stamp, the period of authorized stay expires on that date.
For example, for parents and grandparents who possess the super visa temporary resident visa or letter, CBSA officers will handwrite a date that is 2 years from the date of entry
on their initial visit only.
