ISO Amazing camping spots in Ontario within 8 hours drive of Grey Bruce

Me and a few friends are planning a 4-5 day canoe trip to celebrate the end of school.

We are looking for some great spots in Ontario, preferably Not Killarney, as we have done the Nellie Lake loop and are looking for something different in terms of location.

We are undecided of wether we want to do a canoe trip proper, or a backpacking trip.

Any/all suggestions are appreciated.

Writing this post in a hurry, not as under prepared as it seems.
