A Direction to Leave Canada (form number IMM 1217B) is not a removal order. If you have been the subject of a Direction to Leave Canada, you do not need to apply for an ARC. You may return to Canada subject to normal examination at the port of entry.
If you were deported because of criminal inadmissibility you (most likely) also have to apply for either Criminal Rehabilitation or a Temporary Resident Permit (TRP) to enter Canada legally
As a regulated Canadian immigration consultant, we are authorized to represent our clients follow the right process and help submit the required information to IRCC and determine whether you need to apply for TRP to enter Canada.
Departure Order
If you received a Departure Order and you
left Canada within the required 30 days and
verified your departure with a Canadian immigration officer at the port of exit
If you left the country without verifying your departure, or more than 30 days after the Departure Order was issued, the Departure Order automatically becomes a Deportation Order
