Moved my post down below:
So it looks like a dancing vs coffee making detour, Chevrolet stuffing task at Yonge-Dundas Square being the rb and ofc the U-turn being at the Monkey's Paw. Also saw teams running into City Hall, not sure what that was for, but I would assume that teams picked up their first clue for the leg there.
So that means the detour came after the rb (as teams were searching for directions to Monkey's Paw after the RB) and it also means the U turn happens before the teams even attempt the detour
Also, the U turn location is out of the city core, while all the tasks appear to be in the downtown. Appears to be an odd choice for the location of the U turn (however, it might be to prevent spoilers, as it was indoors).
