Yes, but first we need more information.

Where do you live? There are too many diverse Ontarios to home in on a location. If you are talking about the one in Canada, please name a community nearby.

What kind of grass do you have/want? Some herbicides are not recommended for some grasses.

My theory is, if it's green, it's good. We don't mow until after our violets bloom. I'm not a fan of creeping charlie, but I have some, too.

Seriously, though, if your lawn is green, who obsess over whether it's grass or not? And let your violets bloom. They're gorgeous and any grass won't really need it until after tge violets are over.

I am right near Morrisburg Ontario Canada and I have absolutely no clue what type of grass I have :).

Can you get Weed-b-Gon Chickweed, Clover, and Oxalis Killer where you live? That's what I would use.
