From 1890 until the late 1960's the Government of Canada would give you 160 acres if you cleared the trees and planted all the land to a crop. If you managed to do this inside of ten years you got the option to buy another 160 acres. A lot of people spent the first several years literally living in a hole in the ground. A pit dug down six feet and lined with logs with a rough roof of logs and canvas.
These people, because I assume there was a husband and wife, made it far enough to build a small house. However, perhaps like many others, they discovered that 160 acres was only enough to guarantee back breaking labour and little or no income to improve their lot in life. No money for a larger tractor or better equipment. So they chucked it in and sold out.
