FlightAware has posted a site they call the Misery Map! These show all the cancelled flights, due to staffing issues. It's an interesting and dynamic site, and shows just how much air traffic there is across the US.

This is an expensive helicopter, which takes rich cottagers to their vacation homes.

I love watching the helicopters on the webpage. Little tiny rotors!

A strange flight

A mystery: the helicopter took off in the morning, Aug. 10.

I think I figured it out!

Aug. 8

This was exciting. I noticed a helicopter on the radar. It flew from Ottawa Airport, to Smiths Falls, and then shut off. It says it was headed to Kingston.

Incident with a transport near Pembroke...

Dec. 24 – Sander Geophysics

They were back at it, in January 4th, flying around and around. I emailed the company doing the airplane flyovers, and someone got back to me. It was a bit creepy until I figured them out.

Thanks for reaching out. I am sorry that our flights made you uncomfortable. We were conducting a magnetic survey for research purposes, which involved flying patterns at various altitudes, and it sounds like you were located near one of the patterns that was repeated several times...The aircraft you saw is equipped with magnetometers that measure the earth's naturally occurring magnetic field. These sensors are completely passive and do not emit anything.

I emailed him back and thanked him for getting back to me. Puzzle solved.
