I think just about any profession related to construction or home maintenance is considered essential here, from the little I've read about it. I haven't seen much new construction going on in my neighborhood, but that could just as easily be planned or voluntary. Plumbers, electricians, HVAC, etc. are definitely still working. In any case, I would think the ATS would be considered an important project to continue since the workers aren't prohibited. But these are strange times, with our mayor now saying you shouldn't go for 3.5 mile run, or you might be arrested, even if you're practicing social distancing. So nothing would surprise me.
