Who are these little guys?

There’s always birds hanging out I backyard outside my window and with spring around the corner (or already here? Idk) they’re back full force. It’s nice waking up to birdsong in the morning and they provide great entertainment for a cat (indoors of course) but I don’t actually know much about birds or what these little guys are. I’m guessing finches but idk.

I live in Saskatchewan, Canada.
