The Alberta Act (French: Loi sur l'Alberta), effective September 1, 1905, was the act of the Parliament of Canada that created the province of Alberta. The Act is similar in nature to the Saskatchewan Act, which established the province of Saskatchewan at the same time. Like the Saskatchewan Act, the Alberta Act was controversial because (sec. 21) it allowed the Government of Canada to maintain control of all of Alberta's natural resources and public lands. Alberta did not win control of these resources until the passage of the Natural Resources Acts in 1930.
