Possible sighting video – potential balloons?

Location: Greater Toronto Area, Ontario Canada Time: 4:42 PM EDT

I spotted this in the sky today while sitting outside in my backyard. Excuse the shaky part of the video as I stood up to get a better look. After recording the video it just went further and further away into the distance until it was too small for me to see.

At first I thought it maybe a drone but the movement didn’t seem like one.

I also consider the possibility of Mylar balloons but they seem to be backlit without any shadow as they move about.

Sorry this is my first time posting and I hope I am not wasting anyone’s time. Just wasn’t sure if this is noteworthy or not.

Thanks ✨
