The Natural Resources Transfer Acts were passed by the Parliament of Canada in 1930 in order to give the Prairie provinces (Manitoba, Saskatchewan, and Alberta) jurisdiction over their crown lands and natural resources, a right they were not given when they entered Confederation. The passage of these Acts rendered the Dominion Lands Act obsolete, since these same lands were no longer under federal jurisdiction.
A few small sections of resource-rich territory were excluded from the act, although they would be transferred later. National parks were also excluded - they remain under the jurisdiction of the federal government, and are generally off-limits to resource development.
