I just called the recruiting centre, and the clerk did not know but he went and asked the Med Tech who does the medical evaluations and this is what I got.
Med Tech start their QL3 in Bordon for 16 weeks. Upon completion of this, there are two routes. They either go directly to JIBC in BC (a civilian college) for 8 months to be licensed as a PCP. If the course is not available immediately, Med Techs are sent to do OJT at a CF Base until that course becomes available. All in all, the QL3 training for Med Techs is 12 months, which is why the first contract is 6 years long.
Hope that helps clear the air for other Med Techs.
