The Irvings: The Family That Owns New Brunswick, From K.C. to the Sale That Never Came

The Irvings are the clearest example in Canada of a family that did not just dominate an industry but a province. For most of the twentieth century New Brunswickers bought Irving fuel, read Irving newspapers, worked in Irving mills, shipped goods on Irving trucks and built ships in Irving yards. The empire was private, secretive and integrated to a degree that made it both the province’s economic engine and its most persistent political controversy. It is part of the Canada Company Stories hub.

Who was K.C. Irving and how did he build the empire?

Kenneth Colin Irving was born in Bouctouche, a small Acadian town on New Brunswick’s east coast, in 1899. His father ran a general store and sawmill under the name J.D. Irving. After flying training with the Royal Flying Corps in 1918, K.C. sold Ford cars and in 1924 opened a petrol station under the Imperial Oil banner. When Imperial cut him off, he began importing his own fuel, and Irving Oil was incorporated in Saint John in 1929.

The method that followed was vertical integration on a provincial scale. Irving Oil needed trucks, so he bought trucking firms. Trucks needed tyres and parts, so he bought dealerships. The family sawmill needed timber, so J.D. Irving bought forest land, then pulp mills, then the Saint John shipyard in the 1950s to build its own vessels. By the 1960s the group owned bus lines, hardware chains, construction companies, a newspaper chain and radio and television stations. Each Irving company bought from the others, keeping margin inside the family and making it almost impossible for outsiders to compete in New Brunswick.

The refinery was the crown jewel. Irving built it in Saint John in 1960 in partnership with Standard Oil of California, processing about 40,000 barrels a day at the start, and bought out the partner in the late 1980s. A deepwater crude terminal at Canaport, opened in 1970, let the refinery receive the largest tankers in the world, which gave it a cost advantage over inland competitors. K.C. left Canada for the Bahamas in December 1971 to avoid estate taxes, returning for six months less a day each year, and died in Saint John in December 1992 aged 93.

How was the empire divided among the three sons?

K.C. Irving’s three sons had already been running different parts of the group for decades when he died, and his estate planning, structured through offshore trusts, allocated the businesses along those lines. James K. Irving, the eldest, took J.D. Irving Limited with its forestry, pulp and paper, shipbuilding, transport and retail operations. Arthur Irving, the second son, took Irving Oil with its refinery, retail network, tankers and terminals. John E. (Jack) Irving, the youngest, took construction, engineering, steel fabrication and broadcasting, later grouped as Ocean Capital.

The division was not clean. Each brother kept minority interests in the others’ companies, and the trusts that held the shares were designed to keep the empire together as one economic unit. That worked while the three brothers, who had grown up working together under a domineering father, remained alive and cooperative. Jack died in 2010, and his family’s stake in Irving Oil was sold to the Arthur Irving Family Trust in 2018, finally separating the oil business from the rest.

Reporting by the National Observer in 2016 and others documented a deeper split between the James and Arthur branches, with the two families gradually unwinding shared holdings, ending joint ventures and competing for the same political attention in Fredericton. By the 2020s the Irvings were effectively two dynasties: J.D. Irving under James’s sons Jim and Robert, and Irving Oil under Arthur and his daughter Sarah. The brothers’ deaths in May and June 2024, five weeks apart, closed the chapter in which a single generation had held the empire together.

What is Irving Oil and why did it consider a sale?

Irving Oil is Atlantic Canada’s largest industrial company. Its Saint John refinery processes more than 300,000 barrels of crude a day, making it the biggest in Canada, and supplies fuel across Eastern Canada and the US Northeast, where it is a major exporter of refined products to New England. The company owns Ireland’s only refinery at Whitegate in County Cork, bought in 2016, operates more than 900 fuelling locations and distribution terminals and employs more than 4,000 people full time. In 2018 it said it accounted for more than half of New Brunswick’s export trade, about C$5 billion a year.

In June 2023 the company surprised the province by announcing a strategic review of its future that could lead to a full or partial sale. Arthur Irving, then 92, stepped down as chairman in October 2023. In February 2024 president Ian Whitcomb announced he would leave, and Jeff Matthews, the chief financial officer, was put in charge of the review. Arthur died on 13 May 2024 at Massachusetts General Hospital, and the review continued under the direction of the family trust.

The outcome, announced in January 2025, was that Irving Oil would remain privately held and that Matthews would become president and chief executive. The company has not disclosed which bids it received or why it chose to stay independent, but the decision kept the refinery, the terminal and the Irish business in family hands at a moment when refining margins had been strong and buyers had been circling Canadian energy assets. Sarah Irving, Arthur’s daughter and former executive vice-president and chief brand officer, is the heir to the Arthur Irving Family Trust that owns the company.

What does J.D. Irving do and how big is it?

J.D. Irving Limited is the more diversified half of the empire. Its forestry division owns and manages millions of acres of timberland in New Brunswick, Nova Scotia and Maine, making it one of the largest private landowners in North America, and operates sawmills and the Irving Pulp & Paper mill at Reversing Falls in Saint John. Consumer products include Irving Tissue, maker of Royale and Scotties brands, and Cavendish Farms, the frozen-potato processor. Transport includes Midland Transport trucking, New Brunswick Railway and Atlantic Towing. Retail includes Kent Building Supplies.

The group is run by Jim Irving, James K.’s elder son, as chief executive, with his brother Robert Irving heading the Moncton-based businesses including Cavendish Farms and Midland. It is private, publishes no consolidated accounts and declines most interviews, so its revenue can only be estimated; industry observers generally place it in the high single-digit billions of Canadian dollars a year. James K. Irving died on 21 June 2024 aged 96, having personally overseen the planting of more than a billion trees over his career and chaired the group into his nineties.

J.D. Irving’s forestry dominance has been contested for decades. Environmental groups and some scientists have criticised the use of glyphosate herbicide on Crown land licensed to the company, and a 2015 dispute with CBC over coverage of the issue led the company to file complaints with the broadcaster’s ombudsman, which were dismissed. Crown timber pricing in New Brunswick, where the government sets stumpage rates for licensees including J.D. Irving, is a perennial political issue because the company is both the largest licensee and the largest buyer of private wood.

How did Irving Shipbuilding become Canada’s naval builder?

Irving Shipbuilding’s Halifax Shipyard is the designated builder of the Royal Canadian Navy’s combat fleet under the National Shipbuilding Strategy. The yard won the combat package in 2011, delivered the Harry DeWolf-class Arctic and offshore patrol ships through the early 2020s and was named prime contractor for the Canadian Surface Combatant in January 2015. That programme, now called the River-class destroyer, will build up to 15 warships based on BAE Systems’ Type 26 design to replace the navy’s Halifax-class frigates.

The money involved dwarfs anything else in Atlantic Canadian manufacturing. The Parliamentary Budget Officer estimated in 2021 that 15 ships would cost C$77.3 billion, rising with delays. As of March 2025 Irving had received contracts totalling C$12.87 billion, including an implementation contract for the first batch of three ships, and the government had spent about C$4.92 billion of that by June 2025. Full-rate production started in April 2025 when steel was cut for the first ship, HMCS Fraser, and her keel was laid in June 2026. Saint-Laurent and Mackenzie will follow, with the first ship due in the early 2030s and the ninth by 2040.

For J.D. Irving the programme provides decades of guaranteed federal revenue and several thousand skilled jobs in Halifax, insulating the group from the cyclical lumber and pulp markets. It also makes the family a strategic partner of the federal government, which has consequences for every other issue on which the Irvings and Ottawa interact, from forestry subsidies to the 2025 US tariffs on Canadian lumber and energy that hit New Brunswick harder than most provinces.

Why was Irving media ownership so controversial?

For roughly fifty years the Irvings owned every English-language daily newspaper in New Brunswick, most of the weeklies and a portion of its broadcasting. A Senate inquiry into media concentration in the early 1970s singled the family out, and critics argued that a province whose largest employer also owned its press could not have independent coverage of forestry policy, tax concessions or labour disputes. The family’s reply was that its papers were run at arm’s length and that no one else wanted to own small Maritime dailies.

The broadcasting assets went first: CHSJ-TV was sold to CBC in 1994 and MITV to CanWest the same year. The newspapers lasted much longer. Brunswick News, the J.D. Irving subsidiary that published the Telegraph-Journal, the Daily Gleaner and the Times & Transcript, was sold to Postmedia in a deal announced in February 2022, ending the family’s direct ownership of New Brunswick’s press after decades of criticism. Postmedia has since cut staff across the titles, which has prompted a different debate about whether Irving ownership, for all its conflicts, at least kept the papers staffed.

The media chapter illustrates the empire’s central tension. Integration gave the Irvings efficiency and control, but owning the newspapers that covered them made every decision look self-interested, even when it was not. The parallel with the Thomson family’s long ownership of the Globe and Mail is instructive: the Thomsons kept one national paper as a prestige asset and sold the rest, whereas the Irvings held a regional monopoly until it became indefensible.

How is succession unfolding in both branches?

The two groups now face different succession questions. At J.D. Irving, the third generation is firmly in charge: Jim Irving, in his seventies, has run the company for years and his son Jamie is involved in management, while Robert Irving runs the Moncton businesses. The group has a settled operating structure and a long federal order book, so continuity is the likely path. The risk is the one that always attends private conglomerates, which is whether the next generation shares the founder’s appetite for the business.

At Irving Oil the question is sharper because the review process exposed the possibility of exit. Arthur Irving’s son Kenneth had run the company until an abrupt departure in 2010 that led to litigation within the family; Sarah Irving, Arthur’s daughter from his second marriage, rose to executive vice-president and was widely seen as his successor until she was removed from the executive list in 2023 as the review began. The decision to stay private under a professional chief executive leaves the trust as owner and the family’s future operating role undefined.

What are the main risks facing the Irving businesses?

Irving Oil’s economics depend on a single refinery and on access to the US Northeast market. The 2025 US tariff dispute put that access at risk, and Saint John’s business leaders warned in February 2025 that the city would feel a massive impact if energy exports were taxed. Longer term, the energy transition threatens demand for refined products in the exact markets Irving serves, while the Whitegate refinery in Ireland faces the same pressure under European climate policy. The company’s private status means it has no obligation to disclose how it is preparing.

J.D. Irving’s risks are different: softwood lumber duties, which the United States has levied on Canadian exporters for decades and raised again in 2025; the political sensitivity of Crown land management in New Brunswick; and the execution risk of the destroyer programme, where delays would push costs beyond the PBO’s estimates and strain relations with Ottawa. Both groups also face the reputational risk that comes with regional dominance, where every mill closure or price increase becomes a provincial political event.

How do the Irvings compare with other Canadian dynasties?

The Irvings are Canada’s most concentrated regional dynasty. The Westons operate nationally and across the Atlantic, the Thomsons globally; the Irvings built everything in and around one small province and exported from it. That concentration created extraordinary local power and also extraordinary local dependence, since a decision in Saint John can move provincial GDP.

They are also the most private. Every other major Canadian dynasty has a listed company at its centre: Thomson Reuters, George Weston, Power Corporation. The Irving groups publish nothing, which is why their wealth is estimated rather than known and why their strategic review in 2023 was such a shock. The absence of public shareholders also means the absence of outside pressure for succession planning, which may explain why the question of who runs Irving Oil after Arthur was left open until the end.

Finally, the Irvings show the limits of vertical integration in a small market. The model that let K.C. Irving outcompete everyone in New Brunswick also meant that as the family grew, the branches found themselves selling to and buying from each other across increasingly strained relationships. The structure that made the empire possible made its division inevitable. The Alberta energy story in this hub, covering Suncor and CNRL, offers a contrast: public, Western, and built on resources rather than refining and distribution.

What can founders and investors learn from the Irvings?

The first lesson is that vertical integration is a strategy with a half-life. It builds unassailable positions when markets are small and suppliers are weak, and it becomes a liability when the family that holds the pieces together multiplies and when the public begins to resent the concentration. Founders should build integration where it creates real cost advantage and be willing to unwind it when it stops doing so.

The second lesson is about founder succession. K.C. Irving divided his empire among three sons who had worked together for forty years, and the arrangement held for a generation. It did not survive the next one, because cousins do not share a father’s authority. Families that want to keep an enterprise together beyond the second generation need governance structures, a family council, a holding company, outside directors, that substitute for the founder.

The third lesson is that privacy has a price. The Irvings avoided quarterly scrutiny and hostile takeovers, but when Irving Oil needed to test its value in 2023 it had no public market to consult and no track record of disclosure to reassure buyers. Private companies that may one day sell should behave, in their reporting and governance, as if they were already public.

Finally, government can be a customer and a counterparty. Irving Shipbuilding’s destroyer programme is worth more than the rest of J.D. Irving combined, and it binds the family to Ottawa for 25 years. For founders that is both an opportunity and a warning: the most valuable contract you win may also be the one that most constrains your independence.
