Eddyk,
I have one that is a real cadilac!
it was custom built by a professor at Queens university and includes a spare tire and rim, and even a kickstand which will support the canoe in a horizontal position. it was built to qonquer the Dickson lake portage in Algonquin. if you have done that trip before, you will know what i mean about the ultimate dolly!
right now it is in my shed, taking up space. i am planning to do 1 more trip into Dickson this spring with it, but if you need it anytime, let me know. we are close enough that i can meet you in Newcastle or somewhere along the 401.
