West Humber River - If you play a lot, this could be a three hour run. This particular section used to be dependent on the dam above being open. Currently (2020), the dam is in disrepair and the city leaves it open to prevent any pressure on it. If there is a heavy rain above the dam, it will flow right through and that is your time to shine. The first part is class 2, but the water keeps moving. Close to where the Hospital is there is "Lost Cause" wave. It is a significant hole hidden from prying eyes. Don't miss it (and don't get stuck in it). From Kipling to the forks of the main Branch of the humber there are multiple drops, and narrow creeky sections that are very uncharacteristic of this urban secret. If you get it on a particularly good day, do not miss the opportunity to take a picture (or even walk up and run Toronto's only real waterfall (10 ft plus that is a trickle otherwise and no other realistic access). Many surf opportunities on route.
