About
Hayman Construction Inc. is Ontario's oldest and Canada's second oldest construction firm, founded in 1872 by John Hayman who emigrated from England and arrived in London, Ontario on May 27, 1868. The company began operations in 1872 when John Hayman started working with his brother William under the name 'Hayman Brothers, Masonry Contractors'. By 1887, John's sons had joined the family firm, which operated under the name 'John Hayman and Sons'. In 1913, it was incorporated as 'The John Hayman and Sons Company, Limited'. In 2003, 'Hayman Construction Inc.' was incorporated as a wholly owned subsidiary, and all projects have been run under this name since March 2006. In 2022, Hayman Construction proudly celebrated its 150th anniversary.
Currently operated by fifth-generation members of the founder's family, Hayman Construction has maintained its reputation for construction excellence throughout Southwestern Ontario for over 150 years.
