I am planning a kayak trip for the first week of July on Georgian Bay. It is still in the early planning stages, but the idea is to start at Tobermory and paddle the outer islands along Manitoulin Island and up to Killarney. Experienced kayakers with rough water experience and a solid roll are a must. If you are interested in this trip, let me know.
Here are several reference blogs of trips in the area to give you an idea of what to expect:
