The following passages comes from http://gazette.gc.ca/rp-pr/p1/2019/2019-06-01/html/reg3-eng.html "Canada Gazette, Part I, Volume 153, Number 22: Migratory Birds Regulations. June 1, 2019... ...New concept of possession — concept of preservation introduced ...The new proposed concept of possession is that once birds are preserved according to the criteria set out in the amended MBRs, they no longer count in an individual’s possession limit. This would encourage hunters to preserve birds for future use, thus avoiding waste. A bird would be considered preserved when it is plucked and eviscerated (or the edible portions removed from the carcass), and then; frozen, cooked, dried, canned or smoked, or when mounted for taxidermy..." "Requirement to retain fully feathered wing or fully feathered head of unpreserved birds ...It is proposed that the hunter have the choice to retain either the fully feathered head or a fully feathered wing to remain attached to unpreserved carcasses for identification purposes... ...This requirement would only apply to unpreserved birds, when they are still in the hands of the hunter who harvested them, or are in temporary custody, or have been gifted. It is important to note that a bird that is eviscerated and plucked would not be considered preserved and must have a fully feathered wing or head attached until the migratory game bird is frozen, made into sausage, cooked, dried, canned, or smoked..." Finally some common sense,,, This reduces the bird from possession once processed (...frozen, made into sausage, cooked, dried, canned, or smoked...) rather than having to be eaten or gifted first. Eliminates a lot of confusion about identifying what it is your sausage / ground meat and we no longer have to worry about leaving the wing / head on carcasses in the freezer. Should also discourage dumping of birds since what ever is your freezer will no longer will count against your possession. It should be noted that birds being transported into the USA will still a attached wing to comply with USA regulations.
