So I emailed my visa office to ask how long the arc would take and this is there response today:
Please be advised that applicants who are inadmissible because of previously being removed from Canada require additional review by the delegated authority who can issue an Authorization to Return to Canada (ARC).
There is no service standard for an ARC application to be reviewed. These are processed by the date of receipt. The date currently being processed is September 2016.
Please find below additional information regarding your application for ARC.
When your application is assessed the decision maker will consider, among other things:
. the reasons for the removal order
. the possibility that you will repeat the behaviour that caused the order to be issued
. the length of time since the order was issued
. your current situation
. the reason why you want to enter Canada.
An incomplete or illegible application will be returned without being processed.
There is no guarantee that an ARC will be issued.
