OK, the convention on naming appears to be falling by the wayside. Some cities articles (ie. Toronto, Montreal) are titled as the city's name only while others (Chicago, Winnipeg, Calgary, Vancouver) are burdened with having the state or province following the city in the article title. In response to your omment below:

the "full name" of Toronto is "Toronto, Ontario, Canada", which is unnecessarily long as an article name. Besides, Wikipedia articles use the most common name, not the full name of article subjects, e.g., United States, not "United States of America", and United Kingdom, not "United Kingdom of Great Britain and Northern Ireland". Wikipedia is an international encyclopedia, not a North American one, so the article title should be what readers around the world will think of first, not just those in North America. Many people outside of Canada have not heard of Ontario, even though they know about Toronto. Let's just leave keep it simple, and keep the existing redirect from "Toronto, Ontario" to "Toronto".

........and seeing that you are administrator..........please re-name the Winnipeg, Manitoba, Calgary, Alberta, Edmonton, Alberta, and Vancouver, British Columbia articles to "Winnipeg", "Calgary", "Edmonton", and "Vancouver",  respectively.  Their full names ie. Winnipeg, Manitoba, Canada, are unnecessarily long and readers worldwide know of these cities even if they have not heard of Manitoba, Alberta, or British Columbia. As you suggest, let's keep it simple. We should not imply that Toronto, Montreal, and Ottawa (by the way, both Vancouver and Calgary are larger than Ottawa) are in a different league, so let's say that all Canadian cities of over 500,000 should stand on their own; we'll make up our own rules as we go along. Thanks. I hope you are able to do this soon.
