You might do better posting in the canada or north america forum, and even with a cpl you may find you dont have enough p1 hours for the insurance. Suggest looking for places that offer extended courses that include p1 time, they will have the approprite insurance and therefore may be willing to rent. If you find somewhere, Id be interested to know where and happy to swop notes on my own research as soon as I get around to it. Sadly the place I was heading back to do my p1 time this summer suffered a loss of floatplane and instructor last autumn so Im looking too.
