3 disk shaped UFOs + 1 L-shaped flying object

Barrhaven, Ontario, Canada, 9:30 pm, Sept 1, 2022. Spotted 2 flying disks travelling in sync low in the sky while in my backyard. They were NOT drones. Ran to the front yard to track them, where I saw a third flying disk had joined. All three flying disks stopped and hovered above our house. Then a massive L-shaped flying object bigger than the disks flew up to the 3 disks. All 4 craft seemed to rendevous for a minute, and then the disks disappeared. The L-shaped object hovered around for a bit as if looking for the disks, searched for a bit, then flew off. It was scary. I got my brothers to come out to watch them too. The crafts were nothing like we'd ever seen before. Later I kicked myself for not video taping it, but honestly in that moment I was scared and didn't think to run inside to get my phone. I got a very distinct feeling that the crafts knew I (we) was there watching them.
