Acres International was born from the larger-than-life exploits of its namesake and founder, Henry Girdlestone Acres. A civil engineering graduate in 1903 from the University of Toronto, H. G. Acres, as he was known, pioneered hydroelectric power in Canada. He was one of the first employees of the Power Commission of Ontario, which became Ontario Hydro, and was chief hydraulic engineer on the great Niagara Falls generating station at Queenston/Chippewa. The station was later renamed the Sir Adam Beck No. 1. The company’s largest office is still in Niagara Falls, though the corporate office is in Oakville, Ontario.

After completing the Niagara Falls station, Acres and his friend Dr. Richard Hearn started their own consulting company in 1924. By the 1930s, Acres was trudging over the Himalayas looking for possible sites for hydro projects. He was travelling with another friend, Sir William Stevenson, who became known as “The Man Called Intrepid.”

Since Acres died in 1945, the company has been employee-owned except for two short-lived periods. In the 1950s, the firm was sold to Fluor Corp, a Los Angeles company which was anxious to cash in on the oil field discoveries in Alberta. That relationship did not work out, so a team of engineers led by Norman Simpson bought the company back in 1960, and the firm went on to enjoy its boom period, expanding from 200 to nearly 1,000 employees in a decade.

Flushed with its success, the company went public in 1969 and became the darling of the Toronto Stock Exchange. Shares skyrocketed at a pace similar to today’s high-tech portfolios, from $2 to $22 in six months. A financier called Andrew Sarlos, who was also an employee, persuaded the company to acquire control of two financial companies, Traders Finance and Guaranty Trust. Sigvaldason believes this vision of marrying technology and finance “was a brilliant concept and served as a forerunner for several other consulting companies who pursued similar strategies a few years later.”

Acres’ excursion onto the trading floors lasted only a few years. in 1975 a group of employees again took back control and the firm has remained employee-owned ever since. It is now counted among Canada’s largest 20 consulting engineering firms.

The firm has worked in 111 different countries, doing airports, urban infrastructure, mining and heavy industry projects. It is mostly known for its work in hydro-electric power generation. It is, for example, doing ongoing work on the Karun River in Iran, where the firm has been active since 1977 (its office in Tehran stayed open even during the revolution). The firm is also involved in the $2 billion first phase of a water transfer project in the Lesotho Highlands in southern Africa, as well as in restoring war-damaged dams in Bosnia and Herzegovina, and in the 300-MW Ham Thuan hydropower project in Vietnam. In Canada, one of the largest hydroelectric projects the firm has been involved with is in reviewing the systems along the entire Churchill River in Labrador.

For a company that has staked so much on hydroelectric mega-projects, the future is bound to bring changes. These types of project are falling out of favour because of their social and environmental costs, which are often inevitable when water is diverted at such scale. Sigvaldason agrees that “the demand for those big hydro projects has dropped off very considerably over the last 10 years.” But, he adds, “We just adapt to the market as it is evolving.”

Building engineering skills in the rapidly expanding field of gas thermal power generation, for example, is one strategy the firm has adopted to look after its future. Another major thrust, Sigvaldason explains, is to develop a role in providing consulting services for existing infrastructure, as distinct from Acres’ traditional role of engineering for the construction of infrastructure. To this end, it has started two new companies: Acres Productive Technologies provides “a whole raft” of facilities management services, from capital budgeting, to safety management. Acres Management Consulting is devoted to helping public and private clients involved in privatizing infrastructure.

The firm’s plan is to grow by 15% per year, both by internal expansions and by mergers and acquisitions. “We recognized a while ago that a consulting firm either has to have a certain scale, or be in a niche,” Sigvaldason says. Asked if he thinks the acquisitions will be by Acres of other firms, rather than the other way round, he answers, “Correct.”

Currently 60 per cent of Acres’ revenue comes from power generation, but it plans to even out the spread of business by expanding its mining/heavy industrial and urban infrastructure divisions. Any diversification will be within the fields the firm already works in, rather than beyond. “It’s important not to dabble,” Sigvaldason says. CCE

    Hello; I have been going through old pictures of my father’s. Mr
    Walter Marshall who worked for Acres back in 1949- 1950? But he has pictures if Hydro Dam at Des Joachims just on the Ontario/Quebec border; also Stewartville dam in the Ottawa Valley and Chenaux dam which is also on the Ottawa river. Is it possible for you to tell me if Acres designed these dams. My father has been deceased for some time but I actually live now in the town of Deep River and would like to possibly donate these pictures with some explanation. We did not know anything really about his work at Acres; all I recall is when we moved to Ottawa and he took a job with CIDA and travelled around the world doing water projects. If you could help I would appreciate it. Just so I can get some history right. Thankyou

      I believe Bruce that you might have known my father George Van Horn she he worked at Acres in Niagara and Toronto offices in 60’s and 70’s.

    This article means a lot to me. My dad worked for acres as a Hydro-geologist in the dam in Arnprior Ont, and years later on the Old Man River Dam in Alberta. He recently passed away and I’m only just beginning to appreciate what he did for a living…when it was a mystery to me as a child. He was a great man and father.

    Interesting to read emails from Acres colleagues that I vaguely remember. I joined in 1962 and sort of was retired in 2005 (last year for mandatory 65 year age), but kept on as a hydro specialist and am still considered “part time” (a dinosaur Hatch does not want to part with LOL). I know a lot of the history. I was on commissioning team at Arnprior GS. Archie Cox and JIm Plummer were the leads at site. Hope to hear from some long lost colleagues.

    My father (Claude Martin) worked as a draftsman at
    H. G. Acres in the 1950’s and ’60’s. He went on to become a high school drafting teacher.
