WHAT This be - I have no idea

This is one of the pages, that I was comparing it to for Zelkova

And for the Elm

In the pics from JG

The branches don't seem to have the zig-zag characteristic of the Elm. Also, I'm seeing a slight seperation between bud and stem. The Elm bud lays flat with the stem, while the Zelkova bud tip is raised just a little.
 
WParborist where in Ontario are you? I have never seen more than a couple very rare Chinese elm in this province. If you are seeing a tree with cork-grey bark then you are looking at Siberian Elm (Ulmus pumila) a very common species in Ontario.
 
Looking at the leaves again it looks like leaf photo three is of a different tree than 1,2 and 4. In photos 1 and 2 the base appears mismatched and the leaves are tending towards lancelate (thus characters of U. parvifolia and Zelkova) in photo 3 the leaves are much more ovate.

The buds appear to be close to the stem which would indicate U. parvifolia.

So my conclusion, I do not know. I will check a Zelkova on Tuesday that I know about and see what I can find.
 
Sir:

Those are great links. Thanks.

The trees are close, close, close. Also, there are always some variations within a species, so I don't think any photo could be expected to accurately depict every tree of that particular species.

The leaf base, bud shape, and bark still seem more like Chinese elm to me rather than Zelkova.

But, I hesitate to disagree with you when seeing your avatar.

I'm a fargin retard!

Sorry chinese and Siberian Elm are quite often interchanged for Ulmus pumila. I'll check out the scientific name more closely next time. Sorry!

Oh mrtree, I'm near the Kitchener area.
 
The Kitchener area has some great trees (and Mennonite Sausage) but not alot of Chinese Elms I bet.

The Siberian Elms in Ontario largely originated from the Rockwood(?) Nursery that sold plants via advertising flyers inserted into magazines and papers. Siberian elm was sold as a instant hedge called Wall of China, this I think is where a lot of the confusion comes from. Hedges could be bought for a couple of dollars, you got bareroot seedlings in a small box through the post.
 
Ok - photos are all of the same tree, different parts.

I have enlarged 3 to show the opposite placement
another of pic 3 enlarged

another different leaves photo

i have also enlarged a leave and more isolated it

I will get MORE bark shots

I will get there tomorrow for more photos, any request as what to take?

in the link that Sir Rat provided - i think those leaves have less veins, and scalloped edge count (ya real scientific words here).

hope this helps

It funny the leaves do not appear the same in the photos. In the first there is no assymetry at the leaf base, but there is in photos 2 and 3.
 
ruler in hand - bug spray on - BOY that did not work - i was in error and happened to step into a ground hole of a pack of very nice bees, four of them were polite and showed me, hopping and jumping, to the picnic table on the others side of the park - girl am i paying for these photo now -


so here are more bark and leaves - with a ruler

thanks

cool discussion, I planted a chinese elm in my froint yard two years ago and its going nuts! I can almost watch it grow. I am even starting to see the bark starting to develop
 
The heavy serration of the leaves made me think Zelkova, But the bark looked more like Ulmus parviflora? Then the leaves scaled next to the ruler was the give away for U. parviflora. The ones i used to work on in CA did much better than the ones here in IL (They don't deal well w/ice)
