Here’s a bit of info regarding rules, dates, etc. with regards to hunting in the D.C.F.
It can get a bit confusing but main thing is what Tyler said…Bright colours (don’t forget about the dogs as well!)
The hunting seasons are not simple, the MNRF produces a whole booklet that outlines all the details. But I think what is pertinent: the deer shotgun hunt is just Monday to Friday this week (Nov. 7-11), but there can potentially be other shotgun hunting on Saturday and although there is no gun hunting on Sunday, there can be bow hunting. The bow hunting for deer reopens on Saturday Nov 12.
