Does anybody have a guesstimate as to when the New Brunswick fall season will begin?

I finished my first spring/summer planting season about 3 weeks ago here in New Brunswick. My contractor told me to expect the fall season to start up again on August 14-ish, but the drought/wildfires have caused delays. Do any more experienced planters have an idea of when it will start? I know it's hard to predict, so feel free to give your best guess and I'll remember to take it with a grain of salt.
