Ontario--I thought almost all herbicides were banned from home lawns.
I see that vinegar (acetic acid), certain soaps and iron solutions are allowed.
I had fairly good luck with straight vinegar--not diluted.

My ideas: include 15 minutes of hand weeding in every application.
I also suggest overseeding with a super dense type of chewings fescue--Like "Radar"--for instance. Crowds out weeds over time.
