What does my uncle need to rent 'a small boat with an outboard motor', as suggested in this helpful answer? Even if not required legally, should my uncle seek any extra training or instruction in person, just for his benefit? Does the law really require only the Official Pleasure Craft Operator Card? This card's online status and offering of free retries make it seem lax and deficient, especially for a complete novice satisfying these important assumptions:
I use 'isle' to mean the minuscule islands in my uncle's areas of interest, such as Algonquin Park, Muskoka, and along Georgian Bay (I exclude the Thousand Lakes region because most of its isles are private).
Intending only to explore small isles and to see interiors inaccessible by car, my uncle purposes to boat only where he sees isles or land; he opposes navigating open waters.
My rational uncle can swim, and vows always to wear lifejackets and to renounce alcohol, but has no experience whatsoever with boating (motorised or not) or canoeing or kayaking.
