There are a couple Items that Canada requires that some states do not.

Make sure to have:
1. Proof of Insurance for your boat
2. Bailing bucket
3. 50' throw rope with a floatable device on the end
4. Flashlight
5. I think whistle but I am not sure on this one for Ontario

Don't freak out about getting a big fancy stuff to meet these requirements, Canadian Tire (Department Store in Canada) sells a kit that has all of this in about the size of a quart jar. Herbie has these kits in his lodge boats.
