Alright, I can honestly say I know next to nothing about trees/ shrubs. Unsurprisingly I am having some difficulty figuring out what it is that I have growing in my yard.
It is a little over 7 feet tall and growing fast. Most of the leaves are green, but some of the newer leaves near the top are reddish. The majority of the leaves also seem to have 3 lobes, which vary in proportion (see pics). Location is Southern Ontario, Canada.
