Races in southwestern Ontario
London and Windsor hold most of the calendar, and the rest is scattered through one-race towns between the two lakes — Grand Bend, Erieau, Shedden, Port Lambton, Pelee Island — flat farm concession roads where the only hill is the wind off Erie or Huron.
47 races with a confirmed date across Chatham, Amherstburg, Windsor, Stratford, London, Chatham-Kent, Exeter, Goderich and more, plus 116 that ran last season and haven't announced their next one.
