On fields that have a surrounding running track, such as Molson Stadium and many universities, the end zones are often cut off in the corners to accommodate the track. Until 1986, the end zones were deep, giving the field an overall length of , and a correspondingly larger cutoff could be required at the corners. The first field to feature the shorter 20-yard endzones was Vancouver's BC Place (home of the BC Lions), which opened in 1983. This was particularly common among U.S.-based teams during the CFL's American expansion, where few American stadiums were able to accommodate the much longer and noticeably wider CFL field. The end zones in Toronto's BMO Field are only 18 yards instead of 20 yards.
