I've seen orbs like this in Ontario in different places, also some things that are hard to describe.
The orbs are so brilliant bright either pink / white or brilliant orange and if you stare at them they hurt your eyes / head. They move very mechanically but smoothly, don't make a sound.
If you look at them when they are moving you can see a trail left behind them in your peripheral vision.
I saw one moving west to east that appeared to make a 90 degree turn north to avoid Pearson airspace.
Aliens, new tech or something else I don't know, but they were unlike anything else I've ever seen.
I've seen orbs 4 times. I've seen some other things a couple times too, but they weren't orbs.
