Yeah, we do some wild color bird schemes here.
Most of what I've seen come out of Leading edge are special colour schemes. The Arrow graphics selection will not only allow you to model any Hornet in Standard Canadian finish, but also allow you to model it from any era in its 20 year history in Canadian service, from the delivery of the first one, a B model, in 1982, right up to the current markings arrangements.
You can get access to RonUSMC's free picture posting site through the General Modeling Discusion forum, there's some Canadian Hornet shots in the F/A-18 reference photo album, including a couple of special colour scheme shots I threw in myself. In the case you might want to take a shot at one of those two schemes, decals are available for both in the Leading Edge catalog.
You might like to peek in the F-5 album too, there's a special colour scheme on a Canadian one in there, you can get decals for it through Arrow Graphics.
Your best bets for Canadian subject decals are Arrow Graphics, Leading Edge and Belcher Bits. They're all Canadian outfits and produce excelent quality products.
Glad I could help
