I got lots of weeds of this kind in my back yard. Please see attached
pictures. The roots are white.

It does look like Dallisgrass. But I'm in mid-west Canada. According to
some books, dallisgrass can only be found in southern US.

Appreciate any advice on what it is and how to combat the annoying stuff.

Looks like a fescue grass. How to combat it? Dig it up!
