exclusion order
An exclusion order is a type of removal order. If you get an exclusion order, you can’t return to Canada for one year. But you can’t return for 5 years if the reason for the exclusion order was “misrepresentation”. This means that you said something that was not true or accurate, or you left out information you were required to give.
If you want to return sooner, you need permission in writing from Immigration, Refugees and Citizenship Canada. This is called an Authorization to Return to Canada (ARC).
