Once a fringe back-to-the-land grassroots movement, farmers' markets are considered eco-conscious necessities now that the public demands to know the provenance of the food they consume. An asterisk indicates markets that have undergone a rigorous certification process by the Farmers Markets Ontario group.

That doesn't mean that the other markets are fakes. They just haven't gone through the certification process.

Either way, we advise that you ask vendors the names of their farms and whether they grow their own products. Questions are always good.
