Ontario historical plaques by location — every county, city and district
Plaques by county in Ontario is the oldest way into this collection and still the most useful one. Ontario historical plaques by location follow settlement rather than population: the older the county, the denser the bronze. This page lists every county, city and district in which a plaque has been recorded, and how many stand there.
Counties, and why the county matters
A county is the unit the province itself used when it began erecting plaques, so plaques by county in Ontario is not an arbitrary filing system — it is the order in which the markers were commissioned. Brant, Frontenac and Niagara carry far more than their size suggests, because that is where the settlement and the fighting were. Where a county has since been amalgamated, the plaques stay under the county name that was cast on them. Reading Ontario historical plaques by location therefore reads the province in the order it was settled. The counties themselves have changed shape since most of these markers went up: townships amalgamated, regional municipalities replaced county councils across the Golden Horseshoe, and a few historic county names survive now only on the bronze. Where that has happened the older name is kept, because that is what a visitor reads at the roadside and what the original record used.
Single-tier city entries
A handful of places are listed as a city rather than a county: Toronto, Hamilton, Ottawa, Brantford and the Sudbury pair. Each city outgrew its county structure, and in each city the plaques cluster tightly — a few streets downtown will hold a dozen. Knowing where Ontario plaques stand inside a city is often a matter of a single intersection. Amalgamation complicates this further. Toronto absorbed six municipalities in 1998 and Hamilton five in 2001, so a marker erected in Etobicoke or Stoney Creek now sits in a city that did not exist when the plaque was cast. The entry keeps the municipality named on the plaque and notes the modern one where the two differ.
Northern districts
North of the shield the unit is a district, not a county, and a district can be larger than a small province while holding a dozen plaques. Algoma, Kenora, Rainy River, Thunder Bay, Timiskaming and Cochrane are all district entries here. Distances mean that where Ontario plaques stand in the north is worth checking before setting out. Ontario historical plaques by location is the only practical way to plan a northern trip.
Ontario historical plaques by location: the full list
Every location with at least one recorded plaque, with its count.
Why are some entries counties and others cities?
The unit is whatever the plaque itself was filed under when it was recorded. Most of Ontario is organised by county; Toronto, Hamilton, Ottawa, Brantford and the two Sudbury entries outgrew that structure and are listed as cities. North of the shield the unit is a district. Niagara is the largest entry here with 118 plaques; Sudbury District the smallest with three.
Are the county names current?
Not always, and deliberately so. Several counties have been amalgamated into regional municipalities since these markers went up, and a few historic names now survive only on the bronze. The name cast on the plaque is the one used here, because that is what a visitor reads at the roadside.
What happens when a plaque sits between two places?
It is filed under the municipality named in the location line of the plaque itself rather than under the nearest town. Where the marker names a township that no longer exists, the modern municipality is given alongside it in the location field.
Does every county page list every plaque there?
It lists every plaque recorded here, which is not the same thing. Twenty-four further markers are known but were never photographed, and those appear at the foot of their county page as a separate list rather than as pages of their own.
