Interestingly, everytime I have had a CO make this statement to me over the years, in both Alberta and Saskatchewan, I have requested them to provide this regulation in writing, so that I could read and understand it properly, and to date I have not received it after the fact, or have they been able to produce the regulation upon request.
To be fair, I haven't taken the time to look for it in within the respective Wildlife Acts and Regulations of either province. But since I made the requests, they should be able to provide the information. Until they do, I will consider it as hearsay.
The information that they did provide in writing regarding status indians from other areas hunting in AB and SK, is that there is a Natural Resource Transfer Agreements in both provinces that allows status indians from other treaty areas to hunt game on Crown land anywhere in AB and SK for sustenance and ceremonial purposes, regardless of species, season, gender or size requirement. Private land still requires written permission from the landowner. Hunting restrictions such as closed areas (e.g., mines, National Parks) do apply.
