How Ontario began

Ontario was laid out in December 1834 by Hiram Cook on the southwest quarter of Section 21 of Springfield Township, beside the trail from Mansfield to Bucyrus, and named for Ontario County, New York; the rival village of New Castle was laid out on the same section the same month but faded, while Ontario gained churches, an academy and, in the 1860s, a station on the Atlantic and Great Western Railroad. It had about 200 people in 1880. The Lincoln Highway (1913, later U.S. Route 30) and the General Motors Fisher Body stamping plant (1956) turned the crossroads into a manufacturing and retail center; residents incorporated a village in 1958 to take in the plant, and Ontario became a city in 2001.

Settled 1834 (George Hoover built the first cabin, at Cook's urging), platted December 1834, incorporated 1958 (village), 2001 (city), by Hiram Cook.

Where the name comes from

Named for Ontario County, New York, the native place of Hiram Cook, who owned the land (Wikipedia and Baughman's 1908 county history). Graham's 1880 county history instead says Cook came in 1820 'from a place called Ontario, in Orange County, N. Y.'

Before the town

No Native village, mound or burial is recorded at the Ontario town site. The town grew up on the trail from Mansfield to Bucyrus by way of Galion, which in 1834 was 'only wide enough for the passage of horses and footmen'; the 1880 county history says Indian trails were the only highways when Springfield Township was first settled, and that one trace used by the Wyandot, Lenape (Delaware) and Shawnee ran past Spring Mills, northeast of Ontario, from the head of the Rocky Fork to the Sandusky River. Colonel William Crawford's column followed that trace in 1782. The land lies north of the 1795 Greenville Treaty line and was ceded at the Treaty of Fort Industry (1805).

Nations recorded here: Wyandot, Lenape (Delaware), Shawnee.

Timeline

  1. — Hiram Cook comes to Springfield Township and buys a farm a few miles south of the future town site.
  2. — Hiram Cook plats Ontario in December on the southwest quarter of Section 21; New Castle, laid out the same month on the same section by Frederick Cassell and Adam Webber, becomes its rival.
  3. — John Evans and A. Atwood open Ontario's first store.
  4. — The Methodist Episcopal congregation, which began at Bigelow Chapel and Taylor's meeting house in the countryside, builds the first church in Ontario (Baughman's 1908 history gives 1835).
  5. — The United Presbyterians, founded by the Finney family and other Associate Presbyterians who had met in houses and barns for thirty years, build a frame church; the same year a large brick building is put up for high-school purposes.
  6. — The Presbyterians, whose congregation began at Five Corners in 1822 and moved by way of Pleasant Hill, build a church in Ontario.
  7. — A man who had escaped slavery, sold eleven times, tells his story to an audience at the United Presbyterian church in Ontario, at a meeting arranged by abolitionist Joseph Roe, who lived just west of town.
  8. — The Atlantic and Great Western Railroad, later the Erie mainline, reaches Ontario and establishes a station; Graham's 1880 history dates its first passenger cars through New Castle to 1864.
  9. — The Ontario high-school building closes after receiving students from a distance since 1850 and is taken over by the Masonic fraternity.
  10. — The Lincoln Highway is routed through Ontario, becoming U.S. Route 30 in 1928.
  11. — The Springfield Township School, a Renaissance Revival building designed by Fred J. Porter and D. Roy Virtue, is built at what is now 3560 Park Avenue West.
  12. — General Motors builds a Fisher Body stamping plant in Springfield Township next to the settlement.
  13. — Residents vote on June 25 to incorporate Ontario as a village, bringing the GM plant inside its boundaries.
  14. — Ontario becomes a city on April 30 after its population passes 5,300.
  15. — The Springfield Township School is listed on the National Register of Historic Places on April 24.

Stories

Two towns on one section

In December 1834 two villages were laid out on Section 21 of Springfield Township along the Mansfield-Bucyrus trail. New Castle was platted by Frederick Cassell and Adam Webber, surveyed by John Stewart, and had a tavern kept by Webber and a Lutheran church built in 1838. A mile to the west Hiram Cook platted Ontario in the woods, persuaded George Hoover to build the first cabin, where Hoover kept a blacksmith shop and a few groceries, and built a hotel on the trail himself. Ontario stood higher and sat on crossing stage lines, and its churches, stores and academy drew the country congregations in. By 1880 the county historian found New Castle's church empty and its population about forty, while Ontario had about 200 people.

A village built around a stamping plant

For more than a century after 1834 Ontario stayed a small crossroads settlement, a stop on the Erie Railroad and then on the Lincoln Highway. In 1956 General Motors built a large Fisher Body stamping plant just outside the settlement in Springfield Township. To bring the plant and the development it would draw inside a municipal boundary, residents voted on June 25, 1958, to incorporate Ontario as a village. The town grew through the late twentieth century into a retail and manufacturing center and became a city in 2001.

Ontario Academy

In 1850 Ontario put up a large brick building for high-school purposes. It took in students from a distance for more than twenty years, and Baughman's 1908 county history credits the Ontario academy with much of the town's early growth. Its doors closed in 1874, and by 1880 the Masonic fraternity occupied the building while the town's children went to a new brick schoolhouse on the east side. In 1928 the township replaced its schools with the Springfield Township School on Park Avenue West, which was listed on the National Register of Historic Places in 2003 and has since been converted into apartments.

79% of these days are measurements from a gauge inside Ontario; the rest are estimated from the nearest gauges around it.

48,730 days of records, 1892-12-01 to 2026-10-30. Source: NOAA NCEI GHCN-Daily, 3,240 gauges in and around Ohio. A day is "gauged" when a gauge standing inside the boundary reported it, and the value is the mean of those gauges. Otherwise it is interpolated by inverse distance from every gauge reporting within 50 miles. Nothing is carried forward, back-filled or smoothed. Against NOAA nClimDiv county monthly precipitation over 136,848 complete county-months (checked 2026-11-01): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-11-01 from the Cracked Buckeye precipitation archive. Snow is the softer number — snowfall is measured by hand with a ruler, no agency publishes a gridded county snowfall series, and blowing snow defeats every observer.
