CCD (Colony Collapse Disorder) is a big problem. I grow cone flowers, which I don't particularly like, but the bumblebees do.
Quebec has banned "chemical herbicides" (I don't know what they think the natural ones are made of, if not chemicals.). The province has had a "Pesticides Management Code" since 2003. There are some pesticides that are just outright banned. Dollard-des-Ormeaux, the city in which I live, has banned almost all use of pesticides since 2006. If you can prove you have an infestation, you can get a 10 day permit to have a certified lawn care company apply pesticides. There are all sorts of rules about notifying neighbours, posting little signs, and keeping it away from toys and kiddy pools, as well as not spraying in winds over 15 km/hour and lot of other rules.
We certainly have a lot more "weeds" in the lawns of our condo association, but, as someone else wrote, it's all green.
Here's two photos of the green patch across from my front door.
I see a lot of green with cheerful dandelions and dainty white flowers.
