I have this Canada thistle everywhere and I'll assume it's from my finch
feeder?

Anyway, I read where you can get rid of it by not letting it go to
seed.....is that true?

The "thistle" seed you feed to birds (goldfinches?) is a misnomer. It is not
a thistle but a member of the sunflower family. I've feed it for years with
no thistle problems. Canadian thistles do not come from this "thistle" seed.
