I have heard a few calls today and yesterday, putting them all together they add up to a heard-only yellow-billed cuckoo. (calls heard include cu-cu, cu-cu, and a clear but rather weak k-k-k-k-kidow-kidow-kidow). I cannot get a visual as the calls are very infrequent, also the bird may be going over the cemetary wall into private gardens.
The location is Plot O of Mt Pleasant Cemetary. Plot O is in the west half, about halfway between Yonge and Mt Pleasant, on the south side.
Also several singing blackpoll warbler this morning in this area.
