The plant is an Amur maple (Acer ginnala) sometimes considered a variant of (Acer tataricum), Tatarian maple. The leaves shown in the photos appear to have characteristics of both.
It's a large shrub or small tree. This maple is invasive, so it's considered a noxious weed in the "specially regulated" category.

Late winter or early spring is the best time to prune. Otherwise wait until after the leaves are fully developed.
