CBSA have provided clarification of the terminology used for the three types of workstations in highway border operations. These are:

• Primary Inspection Line (PIL) – describes a workstation where a driver and the CBSA Border Services Officer (BSO) first interact.
• Primary Processing – describes a workstation where the PIL BSO may direct a driver if additional commercial processing is required. This is sometimes referred to as the “front counter” or “commercial counter”.
• Secondary Processing – describes a workstation where the BSO may direct a driver after the PIL or Primary Processing and where examinations are conducted.

This information will also appear on the eManifest pages of the CBSA Web site.
