Aecon Group Inc. - EPC company profile

Aecon Group Inc. — Construction, nuclear refurbishment and energy infrastructure delivery

Aecon Group Inc. is a Toronto-headquartered Canadian construction and infrastructure-development company. Aecon and predecessor entities have carried on business in Canada since 1877. Its construction operations span civil, transit, nuclear, utility and industrial work, while its concessions business develops and operates infrastructure. Aecon delivers selected projects under explicit EPC contracts, including grid-scale battery storage; on other references it is a construction contractor or a member of a project-specific joint venture, so those scopes are described separately.
