Help tree identity
Apologies if I've posted this in the wrong place, but: I recently moved to southern Ontario, an hour north of Toronto, and we have a HUGE tree which we love but can't work out what it is.
Our soil is sandy, get very cold winters and hot summers. I haven't seen this tree anywhere else around here so get the impression that it's not native to the area.
I've attached an image that show the overall size of the tree and close up of the leaves.
Any help would be very much appreciated!!
Many thanks, Rowland
