I'm looking forward to the official answer too. IIRC possession of a fire arm during a legal hunting season is considered proof of hunting. I am under the impression that in Alberta, your license is the paper receipt which goes with your tags. You must purchase a license (and are issued tags with that license) for each species you are hunting. Here are some related clips from tha Alberta Wildlife Act. I would say buy an upland gamebird license and take a shotty, first round is small shot for that grouse, second is buckshot for the bear/cougar.
“hunt” means, subject to subsection (6), with reference to a subject animal,
(i) shoot at, harass or worry,
(ii) chase, pursue, follow after or on the trail of, search for, flush, stalk or lie in wait for,
(iii) capture or wilfully injure or kill,
(iv) attempt to capture, injure or kill, or
(v) assist another person to hunt in a manner specified in subclause (i), (ii), (iii) or (iv) while that other person is so hunting;
(p) “licence” means a valid and subsisting licence issued under section 13(1) authorizing hunting, and includes a tag or other component part of a licence;
Hunting without licence
24(1) Subject to subsection (3), a person shall not hunt wildlife unless the person holds a licence authorizing the person, or is authorized by or under a licence, to hunt wildlife of that kind.
(2) Subsection (1) does not apply to hunting that is specifically authorized by or under the Agricultural Pests Act and, to the extent that subsection
Requirement to carry licence or other proof
26(1) A licence holder hunting wildlife shall carry the licence authorizing the holder to do so.
(2) If a person other than the licence holder is authorized by or under a licence to hunt wildlife and hunts under the authority of that licence, that person shall carry an instrument signed by the Minister or the licence holder stating that that person is lawfully authorized so to hunt.
AKA if you tag out but your buddy still has one, you can assist him as you still have a valid license. No license whatsoever, no helping on the hunt.
