The claim is true because Alberta is uniquely situated on treaty lands (Treaties 6, 7, and 8), and multiple authoritative sources confirm that there is no legal mechanism for the province to unilaterally declare separation without First Nations' consent, given the binding nature of these treaties and Indigenous sovereignty.
Even there were support for this red herring, Alberta unlike any other province has a special status in that it is located on treaty land (treaties 6,7 and 8 specifically) there is no mechanism for unilaterally declaring separation.

What the Evidence Shows
Alberta's territory is covered by several numbered treaties, specifically Treaties 6, 7, and 8, which establish legal agreements between Indigenous nations and the Crown. These treaties confer special status on the land and recognize Indigenous rights and jurisdiction. Sources consistently emphasize that these treaties cannot be overridden or disregarded by provincial governments unilaterally. Furthermore, Indigenous nations assert that any discussion of Alberta's separation from Canada must include their free, prior, and informed consent, as their inherent rights predate the province's creation.
Legal and political analyses highlight that Alberta does not have the authority to secede independently because such an act would violate treaty obligations and Indigenous sovereignty. The province's existence and governance are intertwined with these treaties, which are held in trust by the Crown for First Nations. Consequently, unilateral secession attempts would be legally problematic and likely invalid without Indigenous agreement.
This special status distinguishes Alberta from other provinces that may not be similarly covered by such extensive treaty arrangements. The consensus across academic, Indigenous, and governmental sources is that treaty rights impose significant constraints on unilateral provincial actions regarding separation.
