Aylmer, Ontario is a town in Elgin County in southern Ontario, Canada, just north of Lake Erie, on Catfish Creek. It is 20 km south of Highway 401.
In 2004, a brand new arena, the East Elgin Community Complex, was completed to house the many enthusiastic hockey leagues in town. The Old Town Hall which houses the library, also has a beautifully restored theatre which houses occasional plays. For history buffs, the Aylmer Museum houses an interesting 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 5001-10,000 population category.
