need close up pics of bark and leaves

Need a lot more and closer detail to determine.....individual leaves, any flowers or fruits, even twigs or bark close ups.

Not sure the relevance of the Ontario comment.........

Appears 'Maple-ish'.

Close up pics would help a lot. :-)

They are either London Plane (Platanus x acerifolia) or American Sycamore (Platanus occidentalis).

Yep. Platanus leaves and bark.

Thanks for the responses. I was having trouble attaching photos with detail. Looks like it is a London Plane. Good eye. MD

Habit looks like the frequently seen Platanus x hispanica 'Pyramidalis'. If those are burly areas on the trunks that would fit this one also.

Although the name London plane is in use for P. x hispanica in general there is actually a specific cultivar 'London' named for its prevalence in that city.
