I have to wonder what the county map for Ontario is. I'm sure the cities are leftist - Toronto, Missauagua(sp), Hamilton, Niagara Falls, London, and Windsor are all Liberal or NDP, but outside of that, I'm not sure.
Yeah, I've wondered about that, too.
Since the county boundaries do not follow the electoral districts in Canada it is difficult to tell. Here are my GUESSES in Ontario based on political trends and cultures (some are not legally counties, but independent cities, regional municipalities or districts):
Extreme blue - Toronto
Strong blue - Peel, York, Hamilton, Prescott/Russell
Moderate blue - Essex, Middlesex, Waterloo, Wellington, Halton, Durham, Frontenac, Ottawa, Greater Sudbury, Sudbury (district), Thunder Bay, Cochrane, Algoma, Timiskaming, Kenora, Brantford
Nearly 50/50 - Rainy River, Manitoulin, Nipissing, Stormont/Dundas/Glengarry, Peterborough, Niagara, Lambton, Chatham-Kent
Moderate red - Hastings, Prince Edward, Northumberland, Simcoe, Huron, Perth
Strong red - Renfrew, Lanark, Leeds/Grenville, Lennox and Addington, Haliburton, Kawartha Lakes, Muskoka, Parry Sound, Dufferin, Haldimand, Norfolk, Grey, Bruce, Oxford, Elgin, Brant (county)
