Ya know, acetic acid has been shown to have carcinogenic effects. But lets not get facts in the way of WAGs.
No, 24D does not cause cancer. It has been researched over and over.

24D is fine and no, people did not put so much on that it became a hazard, and no that wasn't the reason ON outlawed it. It has very low toxicity to non-weeds, and especially animals. I had a friend who's dog ate an entire 24D weed bar and the dog was fine.
It is considered the most studied and researched chemical on the planet, not to mention that it has been used for over 50 years. It has been reviewed as part of a class of chemicals that are amongst the most tightly and extensively evaluated, as well as routinely re-evaluated. Plus it is reviewed independently and redundantly across the world with many governments and organizations. Even with all sorts of testing it remains approved for use in Canada and many other places all over the world. The Canada PMRA recently re-reviewed again (and again and again) with approval.
24D banning in ON was another libtard political mouth exercise. There was no safety or health issue around the banning of it. Purely political.
Ontarian's get the type of government they deserve and voted for.
It's totally your choice, I never said 2,4D caused cancer I just said I prefer to use compounds that I know won't cause any adverse affects on my pets. I'm not all that fussed about a few weeds though, like I say, mow anything down and it all looks green.
