See NRR I.A.8, which reads, in part:
Quote:A minimum of a St. John Ambulance or equivalent "Emergency First Aid" certificate is required for all CARS licenced competitors and/or those holding FIA licences issued by ASN Canada FIA, with the following exceptions...
The course you've linked to is the exact one referenced in the NRRs, so it would satisfy licencing requirements.
Please note that this is the bare minimum required. As Alan mentioned, there is additional training that would be valuable to have.
BTW - If you don't need your licence for Tall Pines, you might also consider taking the RSO First Aid course. It will be offered in early 2006 (location TBA) in time for Perce Neige; it satisfies the Emergency First Aid requirements and has additional modules to cover more "rally-related" injuries than the normal Emergency First Aid course.
