I don't recommend using RAID in your tent unless you like huffing spray.

you have a sleeping bag, that's the biggie, I'm sure she'll have everything you need to survive, but it won't hurt to pack 2 towels for yourself, and two pairs of shoes (sandals and shoes will do), bug spray, sunscreen, and bring some old newspapers if you're going to be lighting a fire (it'll save you a lot of grief)..

and once the sun goes down, make sure anything with food in it that you're not holding onto, or sitting right beside you is stowed in the car. a cooler, bag, or putting it in your tent won't keep it safe from racoons. Racoons are your biggest enemy.

other than that, have fun... it's only lake simcoe, so not like you're far away from a bed and breakfast if things turn for the worse...:P
