You hit a deer on a rural highway. Nobody is hurt and the damage looks minor. Is there anyone you should tell?

Correct answer: C. Yes — report hitting a deer or moose to the local police service or the Ministry of Natural Resources

Yes, and not only the police. The Driver's Handbook says that "if you hit a deer or moose, report it to the local police service or the Ministry of Natural Resources." That is a separate expectation from the ordinary collision-reporting rules, and it exists partly for you and partly for the next driver: an injured animal that runs off the road is a hazard someone has to deal with, and the reports build the picture of where collisions cluster. The same section covers what to do before it comes to that — "slow down and sound your horn", "be alert for other animals that may be with the one you've seen", and "don't try to drive around the animal." If you stop to look at wildlife, it says to "find a safe place to pull completely off the road and park first", not on the shoulder, and to stay in your vehicle.
