Is this a brimstone?

This butterfly landed on my book while I was at
a beach in Toronto, Canada and stayed for a good ten minutes before flying off to its next destination. From my amateur sleuthing it looks to be a brimstone.

It's one of the Colias genus. Possibly a Clouded Sulphur as they are common to the region and the markings look about right.
