About

Welcome to Giffin. It is our pleasure to share with you the continuous journey of this family’s owned and operated companies.  From the humble beginnings by Donald P. Giffin to the continued and expanded growth by the second generation; this small sheet metal company evolved to a full service design-build fabricator and erector inclusive of combustion services in Toronto, Ontario.  A formidable Canadian company built on the vision of its founder and its strong dedication of serving its clients in a range of sectors.

Beginning as a small sheet metal shop located on Golden Avenue, Toronto, Ontario manufacturing for the commercial HVAC industry; its production was geared primarily to ventilation ductwork for office buildings and factories.  In 1962, Giffin relocated to a 65,000 square foot manufacturing facility on Bridgeland Avenue, Toronto providing an opportunity to expand the sheet metal services.  This current location also offers an additional 35,000 square feet of outdoor storage/logistic space.

With the new facility, Giffin expanded with a strategic shift toward the industrial sector and automotive market in 1965. This would first begin with sub-contract work with other automotive suppliers before leading Giffin to its first significant, direct automotive contract in 1973 with General Motors in Oshawa, Ontario.  The year 1979 brought an addition to the company’s growth with the introduction of Giffin Contractors.  A facet to propel the company further into the automotive and OEM associated industries offering viable and attainable solutions in paint finishing, metal treatment, energy reduction, pollution control, air handling, air movement and project management. Giffin Contractors provide turn-key solutions from initial design concept, to proactive planning and scheduling to complete their clients’ projects on time.

Giffin Sheet Metals Limited also became specialists in the nuclear power generation program, with contracts from both OPG and AECL to manufacture D20 Vapour Recovery Driers and ductwork for reactors located in Canada and South Korea. This growth brought further work involving the CANDU reactors for which Giffin was the only Canadian manufacturing facility certified for fabrication and installation. 

Diversifying continues into new sectors with manufacturing ventilation and dust collection systems for the food and pulp & paper sectors, to odour control for waste water treatment.  Whether operating solely or collaborating with Giffin Contractors together on automotive and OEM projects including process ventilation and air handling systems, new paint spray booths to dust collection; Giffin Sheet Metals Limited strives to generate innovative and cost-saving measures to all our clientele.   

In 2010, the company expanded further with the addition of Giffin Combustion Services Ltd., a TSSA registered company who specialize in gas fired combustion equipment and thermal systems. This acquisition enabled Giffin to offer further services such as design, engineering, procurement, fabrication, assembly, installation, commissioning and maintenance in the ICI sector as well as automotive and OEM manufacturing. Giffin Combustion Services Ltd. provides extensive experience in all types of ovens, air supply houses and boilers.

This synergy expands Giffin’s portfolio of services as a multi-trade resource. With more than 70 years of experience and growth, this integration provides our multi-sector clientele with turn-key solutions.

Giffin’s commitment to customer satisfaction, our quality culture, our dedicated and energetic staff, our manufacturing facility and vigorous training are all testament to continuing endeavours to deliver our clientele with unparalleled products and services.
