Unknow Bird Song (1 Viewer)

I saw this bird at Mud Lake in Ottawa this morning. It was small, had a grey back and whitish belly with a black patch on the upper part of its breast. I was too far away to get a good photo but I did record its song. Both photo and audio file are attached. Photo won't help much with ID but it gives an idea of size.

Can anyone ID this bird based on its song?

The loudest bird is what you're asking about I presume? If so it's a Song Sparrow

Yes, it's the one that is heard from 0:03-0:06. Thanks for your ID.
