Yes, individuals who have been deemed inadmissible or barred from entering Canada may apply for a TRP if they can establish a valid and justified reason for their visit.
TRP holders cannot work or study in Canada unless they are issued with the respective permits. However, if a TRP is valid for at least 6 months, the visa officer may consider issuing a work or study permit.
If your TRP is cancelled, you will receive a letter explaining the reasons for the decision. You must leave Canada immediately or face deportation. However, you will have an opportunity to respond and address the issues raised before the cancellation takes effect.
TRPs usually allow for single entry, and become invalid once you have departed from Canada. If you need to re-enter Canada and are still inadmissible, you will need to apply for a new TRP. However, at times, officers may approve a multiple entry TRP valid until the specified period or until cancelled.
