Aylmer is a town in Elgin County in southern Ontario, Canada, just north of Lake Erie, on Catfish Creek.

In October 1817, John Van Patter, an immigrant from New York State, obtained 200 acres (80 hectares) of land and became the first settler on the site of Aylmer.

Aided by easy access to Lake Erie, Aylmer became by the mid-1860s the marketing centre for a rich agricultural and timber producing area.

Benefiting greatly from the construction of the 230 km (150 mile) Canada Air Line Railway from Glencoe to Fort Erie, Aylmer became an incorporated village in 1872 and a town in 1887.

He was defeated by the former principal of East Elgin Secondary School, Jack Couckuyt, by a wide margin on October 25, 2010.

For history buffs, the Aylmer Museum houses a collection of 19th century Victorian art pieces created from hair.

In 2007, Communities in Bloom, a nationwide beautification program, awarded Aylmer first place in Canada in the 5001 to 10,000 population category.

The community drew attention during the 2020 COVID-19 pandemic when a local church held drive-in worship services where parishioners remained in their vehicles.

The services were considered by Aylmer Police to be in possible violation of provincial restrictions on public gatherings but they opted not to levy fines of up to 100,000 CAD.

A number of members from this community participate in the weekly Aylmer Sales Barn and sell fruit, vegetables, eggs, and animals, such as rabbits and chickens.

In 1959 the Attorney General appointed an advisory committee on police training in 1962 announced the formal establishment of the college.

OPC offered its first classes beginning January 7, 1963, in the temporary wartime training quarters of an abandoned Royal Canadian Air Force base near Aylmer, Ontario.

With very rare exceptions, all Police Officers in Ontario, Canada attend the college for their 13-week program in order to receive their Basic Constables Training Diploma.

Farmers and others complained that throughout the preceding years, the extravagant attractions that were created leveled the significance that agriculture and livestock was given.

A turnover in personnel and the government granted more funding, this turning point created major changes in attractions and promotions over the next six years.
