This market will resolve to "Yes" if Google Maps displays "Lake America," "Lake of America" or similar as the label for the body of water currently known as the "Lake Ontario" for the majority of users within the United States by the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. Changes which appear only in experimental features, beta versions, or subnational regional variants, will not qualify for a “Yes” resolution. If both "Lake America" and "Lake Ontario" are used to label the body of water, this will qualify for a “Yes” resolution. The resolution source will be Google Maps (maps.google.com) however a consensus of credible reporting may also be used.
