About PR status renunciation
While for most people the status of the Permanent Resident of Canada is a dream and a goal they are trying to achieve, in certain cases some people need to renounce their status of the permanent resident of Canada.
Such cases are mostly boiled down to the situations when permanent residents of Canada abroad did not comply with the residency requirement, and they have the need to enter Canada as visitors, students, workers.
To be treated as foreign nationals, such people must first renounce their permanent resident status to avoid problems with the border officer after they arrive in Canada.
When their permanent resident status is cancelled, such individuals may again be treated as foreign nationals and may apply for temporary or permanent residence depending on their current plans and intentions.
