If planning a hunting trip in Canada, there is quite a lot of paperwork and regulatory hoops to jump through before entering, and it can be prime picking when it comes to bird gaming. Canada has a strong hunting and gaming culture, and you can have a blast (no pun intended) by gaming for fowl. Here are a few things you need to know before embarking on a hunting excursion further north.
An additional permit is required for whatever bird you are going to hunt. This will be a card for both fishing and hunting of any kind. If hunting in Ontario, for instance, you will be required to purchase an outdoor card for $9, which will last 3 years. The main purpose of this card is to show proper identification to the proper ranger or park officials, since all pertinent hunting information will be on the card, and you won't need to show ID of any other kind. You can purchase the cards online and print them in e-card format.
One of the harder barriers you'll have to overcome is Canada's stringent laws when bringing firearms into the country. Fully automatic weapons and handguns of any kind are not allowed, and there are some restrictions on rifles and shotguns. Rifles and shotguns with a barrel shorter than 18 inches, and an overall length shorter than 26 inches, is prohibited. Ammo must have a minimum weight of 100 grain, and .22 caliber rounds are not allowed.
You can obtain a Possession and Firearm License (lasting five years), and will cost $60. This is not a requirement, but it will take longer going through customs without it. If you don't go for the firearm license, you can take the time to fill out a $50 permit application that will last one year.
Since we're talking about waterfowl hunting, the application process for hunting birds is less stringent than hunting big game animals in Canada. The good news is that you're allowed to bring back game you hunt in Canada back to the US, but you must have at least one fully feathered wing on the carcass for proper identification until you reach your home, or a taxidimery/processing center. You can also mail any killed game to the US, provided you state on the outside what is in the package and how many birds there are inside.
When it comes to bird hunting in Canada, there are no real tight restrictions. All duck species are allowed, along with sandhill cranes, geese, Hungarian partridge, ptarmigan and ruffed, sharp-tailed and spruce grouse.
