It's a CH-149 Cormorant, the CAF version of the Agusta EH101 Merlin. You'd probably have to convert from the latter type. Belcher Bits did a 1/48 conversion set for the Airfix kit -- including decals -- but there may be other options. For those, you'll probably have to source the decals from one of the Canadian aftermarket companies like Leading Edge.
A good Google search should turn up your options.
