Ontario Whitetail Deer Hunting Deer are all over Ontario. Just about everywhere you go you will see deer feeding on the side of the road or in fields. The most common deer in Ontario is the White Tailed Deer. We do not have an organized deer hunt so deer hunters just pay for the regular cabin or camping rates. Deer season is from November 1 to November 13. Tags are obtained by the Ontario Lottary System. Due to a population explosion of Whitetails in Northern Ontario, tags are very easy to obtain and the hunting is good.
