I am looking for factual information, not opinions, on the legality of using the .223 Remington and 5.56mm cartridges for deer hunting in each province and territory in Canada. My Facebook feed is crawling with antis who are going ape dung about semi-automatics and the AR15 rifle right now. I want to counter and educate these people with facts... which I know the antis will largely ignore, bit I have to try. Here in Nova Scotia, the .223 and 5.56mm cartridges are ILLEGAL to use for deer hunting as the minimum cartridge used to hunt deer must be .23 calibre. Please let me know what province you are from and whether you are legally permitted to use either of these cartridges to hunt deer. Thank you!
