As a truck driver doing a run from Winnipeg to Edmonton, I have hardly seen any deer roadkill the entire summer. I've seen maybe 1/2 dozen deer in the last week dead in the ditches, mostly bucks (when I could see anything left of antlers.
I do the same run every week, so my observations are fairly consistent. I don't see the herds of deer out in hayfields either. Might be too soon for them to do that, yet.
What I have been seeing since late summer is a lot of dead coyotes (and some large red sprayed "splotches" in the driving lane) along the highway, and quite a few hunting the shoulders of the highways.
