Ontario, Oregon
Ontario was founded on June 11, 1883, by developers William Morfitt, Mary Richardson, Daniel Smith, and James Virtue. In March 1884, Richard Welch started a post office for the quarter of Ontario, so named by James Virtue after Ontario, Canada. Two months later Joseph Morton applied for a Morton post office at an island about one mile south of town, with Oscar Scott as postmaster. Unfortunately for Morton and Scott, merchants Morfitt and Richardson of Malheur City, gold miner Virtue, and lumberman Smith of Baker City acquired more land and were better financed. More importantly, Morfitt had negotiated a train depot for Ontario. All the settlers and speculators knew the railroad was coming and how important that would be to Ontario's future so Scott closed his Morton post office and built a hotel at present-day Ontario. By December, Scott was Ontario's postmaster.

Upper Canada was a name given to areas in present day Ontario in the 18th and 19th centuries, until 1840 or 1841, when the Province of Canada formed. In 1867, this also no longer existed with the Confederation of Canada when Ontario and Quebec became officially named, and became two of the four provinces of Canada.
