 It became known as Clearbrook by the late 1940s, most likely named after Clearbrook Road, a road that originally ran from Old Yale Road south across the Canada-USA border to nearby Clearbrook, Washington.The area was heavily logged in the early 20th century by the Abbotsford Lumber Company and other smaller logging firms which left behind nothing but large stumps and small trees.In 1931 Mennonite immigrants who had migrated to Canada from the USSR in the previous decade began settling in the area.
