Concession road

In Upper and Lower Canada, concession roads were laid out by the colonial government through undeveloped land to define lots to be developed; the name comes from a Lower Canadian French term for a row of lots. Concession roads are straight, and follow an approximately square grid, usually oriented to a local lakeshore. They are 100 chains or 1.25 miles (2.0 km) apart, so that two consecutive north-south concession roads and two consecutive east-west roads enclose 1,000 acres (4 km²). These 1,000 acres (4 km²) were then divided into lots according to various plans.
