Bugs generally aren't all that bad this time of year in Canada, but they are there none the less. As for the weather - YES it has a pretty dramatic effect on the rutting activity of bulls. When it gets hot in the late morning and early afternoon, the bulls pretty much shut down and stop moving and calling. It can get pretty tough, but your early mornings and late afternoons are still pretty productive if you stick close to some good water sources.
Whereabouts in Ontario are you headed? My dad is leaving Thursday for his moose hunt just north of Perrault Falls, Ont. I went last year, but I just couldn't come up with the cash this year - my little 5 month old at home took all of my hunting slush fund.
