I live in Gaspe, Quebec.
Q. false sunflower leaves turn yellow and curl up
What is causing my false sunflower leaves to turn yellow and curl up? Inside the curled leaves are small black eggs, and I found a worm on one leaf. I do not want to spray them with anything that will kill birds, however. The flowers will not be blooming for a week or so.

It would appear that eggs have been laid in your plant leaves.
I understand wanting to protect all the beneficial insects, bees and birds.
Neem Oil would be a good treatment.
Here are a few links.
