I think this is a weed with my helenium double trouble. Can you help?

These two are the questionable plant

This is the helenium

The stems are different. The mystery has smoothe round stem. The helenium has stripes and a "fin" on the stems

The base of the two next to each other

The leaves are similar. But not quite the same

First thing I thought of was Goldenrod when I saw the photos.
Could it be Solidago canadensis?
