I think that your question about the numbers of how many helos are at each unit is bordering on operational security issues (thus the reason why you can't find this info), especially with a former unit of mine that does not discuss these sorts of things. Others may feel comfortable answering with specific numbers, but I don't and quite frankly I'm not sure why you need to know. However, I will speak in generalities. Larger units are 403, 408, 427, and 430 Sqns. Smaller, but not less important, are the Combat Support Sqns in Cold Lake, Bagotville, and Goose Bay and of course 400 and 438 Sqns. Plus, there are some Griffons at other locations, but not in large numbers.
400 Sqn (Borden) is now an Air Maintenance Sqn for the Griffons and 438 Sqn (St. Hubert) is a Total Force unit. Both have mixtures of Regular and Reserve force members. So, to answer your somewhat confusing question, yes, there are Regular force members at both units and yes, they only operate Griffons at those units. Also, some Reserve force mbrs are "full time", i.e. Class C.
