Depending on what visitors say at the border and the documents they have with them, an officer may decide that more information is needed. If this happens, the visitor may be sent to “Secondary Processing” where he or she will be seen by an immigration officer.

If there is a business relationship in place, your letter of invitation can explain the reasons for a visit and help prevent this from happening. Also, when the Canadian business provides 24-hour contact numbers, they can answer questions about the visit.

If, for example, the visitor is coming to service a piece of equipment as set out in a contract, he or she should bring a copy of the contract or bill that states that this work is covered.

- CBSA agents are like NBA referees, the lower their number, the more experience they have. IF you have the opportunity, see if you can get an agent with a lower number on their chest. The numbers are into the six figures. 200000 and above are fairly new people, the lower you can go, the better the experience.
