I finally found a list of all the parties and there is also at the Elections Ontario site addresses, emails, and websites for all the parties.
A CBC article noting that there are 12 parties does not even list them or indicate any of their policies. Since the minor parties have no seats, in a market based system the press pays them no attention. I have posted a bit about Green and Communist policies but the party websites would be the best place to get info on policies. Some parties such as the Libertarian Party are reasonably well known but others are less so. It is interesting that it is the Ontario Progressive Conservative Party that is running not the Conservative Party -the federal name.
