Simcoe was Named for John Graves Simcoe in 1795, the first Lieutenant Governor of Ontario. Originally two separate hamlets, the current downtown started as Birdtown, named by William Bird, who settled in the early 1800s. The north end of town, currently known as “the Queensway”, was originally called Theresaville (in honour of Robert Nichol’s wife), as it grew around Aaron Culver’s saw and grist mill in the 1820s. When the post office was established in 1829, Culver’s suggestion of Simcoe was approved.
In an Irish pub, patrons toast each other sláinte (pronounced "slaan-sha") as they clink glasses of Guinness. Derived from the Old Irish adjective slán (which means "safe"), sláinte literally translates as "health" and is used as a stand-in for the more time-consuming "I drink to your health!"
