Business Number + import/export (RM) account
The legal prerequisite for any commercial import — a BN with an active RM account.
- 01Register for a Business Number (BN9) via CRA Business Registration Online if you don't already have one.
- 02Add the import/export (RM) program account — since Oct 21, 2024 new importers with a BN9 can do this inside the CARM Client Portal.
- 03List every legal/trading name that appears on invoices and customs paperwork on the account.
- 04Expect same-day to a few business days for BN9; RM activation in CARM is near-instant once the BN9 exists.
Most-missed
A GST/HST (RT) account is not enough — you specifically need the import/export (RM) program account.
