Unfortunately there were no twigs anywhere near the ground so this is the best I could do. I tried searching for compound alternate leaflets.. nothing seemed to be matching up. It's in southern Ontario. Thanks!

I can't seem to find an elm with buds that stick out at 90° from twig...

Through other channels it's been hashed out to be a Siberian Elm. Which when I look at photos of the twigs with leaves on, looks much more likely that that could be it. Thanks for the help!
