I thought this Acer platanoides 'Crispum', also called 'Laciniatum' or Eagles Claw Maple, was the one described by Gerald Straley in Trees of Vancouver, at Lagoon Drive in the Stanley Park Pitch & Putt. It's just a bit north of the entrance, very close to the Atsumori cherry I was really looking for. But I don't think that's the NW corner of the golf course where he said the only one seen in the city is, so maybe there are two, as I'd call this the south corner. Straley describes it as "certainly more of a curiosity than attractive". This one gives the appearance of being sick, with all the leaf edges curled under.
