The Dominion Land Act of 1872 offered agricultural pioneers an opportunity to "prove up" a quarter section of land (160 acres/65 hectares) in western Canada for a $10.00 filing fee and three years of improvements combined with residence on the land. Saskatchewan still has cattle ranching along its southwestern corner; grain farming and crops such as wheat, oats, flax, alfalfa, and rapeseed (especially canola) dominate the parkland area. Mixed grain farming, dairy farms, mixed livestock and grazing lands dot the central lowlands region of this prairie province.
