Candle Lake is forested Canadian Shield. At that time of year the lakes will be frozen over, there should be snow in the bush and roads, and temperatures will be cool. Temperatures should actually be well below the 32 degrees mark. Plenty of deer in the area, however, there is a huge no-shoot zone in the area.
I have relocated to the Himalayas, otherwise I would dig out some maps and advise you of where to go. Be careful where you shoot! Your friend should know where it is legal to hunt (I think the main highway is the dividing line). I would probably recommend hunting a little south of that area in the parklands, but I am sure that the person you are staying with knows the lay of the land, and the best areas to hunt there. Good luck!
