A removal order is issued at the start of a refugee process but stayed until a decision is reached. This order would come into force when the guy didn't show at the hearing. From the CBSA website:
If a person is issued a removal order and files a claim for refugee protection, the removal order does not come into force until the claim has been decided. If the claim for protection is accepted, the removal order is cancelled. Unsuccessful claimants who had conditional departure orders issued against them must leave Canada within 30 days of the date of the final determination of the claim or the order becomes enforceable.
If he left and wanted to return to Canada, he would have to apply for Authorization to Return to Canada (ARC).
Thanks for making that clearer
