What could this be?

There seems to be enough irrigation. No pets around. No white grubs.

First few look like dollarspot fungus. What kind of grass is this?
Brown rings look more like necrotic ring spot.

Thanks!

Typical cool season grass (kentucky, ryegrass, etc).

So a shot of EAGLE 20 EW would probably help?

A fungicide would help.
Eagle is good for dollarspot.

Necrotic ring spot is difficult to control. Are you allowed to use chemicals in Canada?
