Alberta’s Richest Families and Their Fortunes

Alberta’s biggest fortunes did not come from one business model. They came from cleaning up oil-field waste, reading geology, laying cable into homes, renting trailers, operating pharmacies, and moving earth with horses before Alberta became a province.

If you want to understand who has shaped the province’s economy, look beyond oil wells alone. These families and business leaders built companies that touch energy, telecom, sports, construction, housing, railways, health care, and philanthropy.

Why Alberta’s wealth stories are rarely simple

Alberta’s resource economy created huge opportunities, but drilling for oil was never the only way to profit. Some of the people on this list made their money by owning the services, infrastructure, or assets that keep the industry moving through good markets and bad.

That context still matters. Alberta holds much of Canada’s oil-sands wealth, and its economy remains closely tied to resource production, transportation, and export markets. For broader context, see Alberta’s role in Canada’s resource economy.

Private family wealth is difficult to verify. The figures below are estimates, not audited financial statements, and they can change with company valuations, commodity prices, asset sales, and public market movements.

Here is a quick view of the ranking and the businesses behind it.

The order reflects the video’s focus on long-running Alberta dynasties, not a strict net-worth ranking. Daryl Katz, for example, has the largest individual fortune in the group.

8. The Werklund family built wealth on oil’s cleanup work

David Werklund found value in the industry’s leftovers

Oil and gas operations create more than production revenue. They also leave behind contaminated soil, drilling mud, produced water, tank bottoms, and other material that must be handled under environmental rules.

David Werklund built businesses around that constant need. While many Alberta entrepreneurs competed to find the next productive well, Werklund focused on the work that came after drilling, transporting, storing, and closing sites.

That business approach was less glamorous than exploration, but it carried an advantage. Oil companies need waste-management and remediation services when they are expanding, and they need them again when they shut down or reclaim sites.

Tervita worked across oil-market cycles

Werklund’s companies grew into Tervita, an environmental and waste-management business with deep ties to the oil and gas sector. The model did not rely on predicting where oil prices would go next.

When prices rise, drilling activity often increases and creates more industrial waste. When prices fall, operators cut spending, abandon projects, or close facilities, creating cleanup and reclamation work.

“He wasn’t betting on the price of oil. He was betting on the fact that industry is always dirty.”

The Werklund family fortune has been estimated at about $1.5 billion. It is a different kind of Alberta wealth story, built around the costs and responsibilities that come with extraction.

7. The Markin family combined energy with health philanthropy

Allan Markin helped build Canadian Natural Resources

Allan Markin is one of the major figures behind Canadian Natural Resources, one of Canada’s largest oil and gas producers. He spent years as chairman and held a lower public profile than some of the company’s better-known leaders.

Still, a quiet profile should not be confused with a small role. Canadian Natural Resources became one of the central corporate forces in Alberta energy, and Markin’s connection to the company placed him near the center of that growth.

The Markin family fortune has been estimated at more than $1 billion, though no public figure can fully capture the value of private holdings and long-term investments.

Much of the family’s influence is in health care

Markin has directed substantial giving toward health and wellness in Alberta. His support has included mental health, addiction, chronic pain, and preventative care.

Those causes do not always produce a visible monument or a ribbon-cutting moment. Preventative programs can be harder to promote because their best result is often something that never happens, such as a hospital admission or an untreated illness.

Across Alberta, large fortunes often flow back into health and education close to where the money was made. The Markin family’s story fits that pattern, pairing energy wealth with long-term support for community health.

6. The Riddell family turned geological judgment into an energy empire

Clay Riddell understood the rock beneath the deal

Clay Riddell began as a geologist, and that gave him an edge in an industry full of financiers, promoters, and technical experts. He could evaluate geological information himself instead of relying entirely on someone else’s view of a prospect.

In 1976, Riddell founded Paramount Resources. He grew it into a major oil and gas company, and the family’s wealth has been estimated at more than $1.5 billion.

Riddell also held an ownership interest in the Calgary Flames. At Alberta’s highest levels of wealth, energy, professional sports, and real estate often overlap.

The family divided leadership instead of leaving a vacuum

Clay Riddell’s succession plan is one of the clearest parts of his legacy. His son, Jim Riddell, became president and chief executive of Paramount Resources. His daughter, Sue Riddell Rose, took leadership of Perpetual Energy.

That arrangement gave each operating company a defined leader. Many founders talk about succession but resist handing over control until the last possible moment. Riddell put the next generation in place while the businesses could continue operating with clear lines of authority.

Clay Riddell died in 2018. Paramount continued to operate and later expanded through the acquisition of Canadian assets from an American producer. The family story rests on a practical skill: understand the ground, build the company, then plan for who will run it next.

5. The Shaw family saw that the cable wire was the asset

J.R. Shaw started with a small Alberta cable business

In the 1960s, J.R. Shaw began a cable television company in Alberta. At the time, cable was largely seen as a way to improve television reception, not as the foundation for a national communications company.

Shaw saw the bigger opportunity in the physical network. The wire running into a customer’s home could carry television at first, but it could later carry phone service, broadband internet, and other services consumers had not yet imagined.

That physical connection gave the business lasting value. Content providers could change, but the network remained the route into the home.

Shaw Communications became a national company

The small cable company grew into Shaw Communications, one of Canada’s biggest telecommunications firms. The family retained control through a share structure that limited the ability of outside investors to take over the business.

In 2023, Rogers acquired Shaw Communications in a transaction valued at roughly $20 billion in the video’s account. The deal ended the Shaw family’s role as operating owners of the company they had built over decades.

J.R. Shaw died in 2020, before the transaction closed. Yet his name remains highly visible across Calgary through philanthropic projects and institutions. The sale turned a regional cable operation into one of the biggest business exits in Canadian corporate history.

4. N. Murray Edwards built his fortune by buying in downturns

A dry well changed Murray Edwards’s approach

N. Murray Edwards is the lone individual in this lineup rather than the head of a multigenerational family dynasty. He grew up in Regina, worked summer jobs refereeing hockey and collecting garbage, attended the University of Saskatchewan, and later earned a law degree in Toronto.

Edwards initially planned to practice law. He changed direction at age 28 after making a promise to a dying friend, according to his own account.

His early move into oil did not go well. An oil well he backed came up dry. Instead of continuing to chase discoveries, Edwards shifted toward buying companies and assets that already had proven resources.

He became known for buying when others sold

Edwards built his reputation by moving against the mood of the market. When oil prices fell and competitors faced pressure to sell, he looked for valuable assets at lower prices.

That strategy demands patience and a willingness to buy while prices are still declining. It also requires enough capital to act when many other buyers have pulled back.

His major holdings have included Canadian Natural Resources, Ensign Energy Services, and Melcor Aerospace. He also co-owns the Calgary Flames and owns Resorts of the Canadian Rockies, which operates several ski resorts.

Estimates have put Edwards’s wealth between $2 billion and $3 billion, depending heavily on energy markets. The hockey referee who once earned pocket money at the rink later became part-owner of an NHL franchise.

3. The Southern family turned $4,000 and 15 trailers into ATCO

Alberta Trailer Hire began as a family bet

In 1947, father and son put in $2,000 each and bought 15 utility trailers to rent around Calgary. They called the business Alberta Trailer Hire, a name that later became ATCO.

Ron Southern was still in high school when the business started. After earning a science degree at the University of Alberta in 1953, he returned to the company full-time and eventually served as president for 48 years.

The basic idea was straightforward: rent useful equipment to customers who needed it. Over time, however, the company expanded far beyond trailers.

ATCO took modular housing around the world

ATCO became known for workforce housing and modular buildings. When a project requires hundreds of workers to live in a remote location, someone has to build the accommodation, transport it, install it, and keep it running.

That business put ATCO in places far beyond Calgary. Its work has included oil-sands facilities in northern Alberta, construction projects in Abu Dhabi, and shelters in Antarctica.

The company has reported total assets around $18 billion and employs thousands of people. The family’s personal fortune has been estimated between $2 billion and $2.5 billion.

Fifteen rental trailers became an international company with projects in the oil sands, the Middle East, and Antarctica.

Spruce Meadows became a second family institution

In 1975, Ron Southern and his wife, Margaret, built Spruce Meadows on the edge of Calgary because their daughters, Nancy and Linda, were serious competitive riders.

Show jumping might have seemed an unusual fit for a city associated with the Stampede and rodeo. Yet Spruce Meadows became a leading international equestrian venue, welcoming athletes from more than 60 countries and millions of spectators over the years.

Ron Southern died in 2016 at age 85. Nancy Southern became chair and chief executive of ATCO, while Linda Southern leads Spruce Meadows. The family kept both parts of the enterprise connected to the interests that helped build them.

2. The Katz family created Alberta’s biggest individual fortune

Daryl Katz expanded a pharmacy investment across Canada

Daryl Katz grew up in Edmonton, attended Jasper Place High School, and earned a law degree from the University of Alberta. In 1991, he and his father invested $300,000 to acquire the Canadian rights to the Medicine Shoppe pharmacy franchise.

Katz continued to buy and expand. He acquired Rexall, added Pharma Plus, and built the Katz Group into an owner of hundreds of drugstores across Canada.

Pharmacy retail lacks the drama of oil exploration, but it has a dependable base of demand. People need prescriptions regardless of whether oil is trading high or low.

The video cites an estimated fortune of about $7.2 billion for Katz, placing him well ahead of the other individuals associated with Alberta. The ranking places him second because its top spot focuses on the historical depth and influence of a family dynasty.

Owning the Oilers brought a public fight over the arena

Katz bought the Edmonton Oilers in 2008. His ownership became tied to one of Edmonton’s most debated civic projects, the downtown arena that became Rogers Place.

Critics argued that public money helped support an arena tied to a billionaire’s team. Supporters argued that the project gave neglected parts of downtown Edmonton more activity, new development, and a major gathering place.

Both views remain part of the arena’s legacy. Katz also expanded into film financing through Silver Pictures, adding Hollywood to a business career rooted in pharmacies, retail acquisitions, and professional hockey.

1. The Mannix family has shaped Alberta for more than a century

The documented story starts with horses and railway work

The Mannix family is one of Alberta’s most private business dynasties. Public profiles are sparse compared with the attention around sports owners or public-company executives, even though the family’s businesses have shaped construction, railways, energy, real estate, and resource development for generations.

The family fortune has been estimated at about $3.3 billion. Its origin story reaches back to 1898, seven years before Alberta became a province.

Family lore says Frederick Stephen Mannix won an earthmoving machine in a poker game. The documented business history is more grounded: he bought a team of horses and took an earthmoving subcontracting job on Canadian Pacific Railway branch lines. A biographical record of Frederick S. Mannix traces the beginning of his contracting business to that year.

Illness and war tested the first generation

Frederick Stephen Mannix faced severe personal and financial setbacks. He was diagnosed with diabetes in the 1930s and lost both legs in the early 1940s.

During the Second World War, the family needed capital. In 1943, it sold a 51 percent controlling stake in the company to an American firm from Idaho, with one key condition: Frederick C. Mannix, the founder’s son, would remain president.

That condition mattered. In 1951, Frederick C. bought the company back from the American owners. His father died later that year, with an estate estimated at about $1 million.

Loram reflected a long-term family outlook

Frederick C. Mannix expanded the business into the Loram Group, a name connected to “Long Range Mannix.” The wording fits the family’s approach. Mannix businesses tended to be built and held over decades, rather than traded for short-term gains.

Loram Maintenance of Way became one of North America’s largest railway maintenance and equipment companies. By 1983, Frederick C. Mannix owned or controlled a network of 132 companies, according to The Canadian Encyclopedia’s profile of Frederick Charles Mannix.

The group also helped launch careers beyond the family. A young lawyer named Peter Lougheed worked for the Mannix organization before becoming Alberta’s premier.

The family later sued Lougheed’s government

That connection led to an awkward chapter in the 1970s. Lougheed’s government expropriated land from a Mannix ranch to create Fish Creek Park in south Calgary.

The Mannix family sued the government for $41 million. The dispute later settled for $7 million.

The episode captures the family’s independence. A former employee had become premier, but the family still fought his government when it believed its property rights had been compromised.

Two sons split the empire, then sold major assets

Frederick C. Mannix became one of the first two living inductees into the Canadian Business Hall of Fame. During the 1970s, he divided the empire between his sons.

Fred P. Mannix took control of what became Mancal. Ron Mannix took Coral Holdings, with interests across coal, oil and gas, construction, real estate, and railway maintenance.

In 1997, the family sold major energy assets, including Manalta Coal, Pembina Pipeline, and Pembina Resources, for more than $2 billion. The businesses were not sold because they had failed. The family used the sale to simplify estate planning after decades of ownership.

A year later, the family endowed a charitable foundation with $100 million. That sequence, built over a century, helps explain why the Mannix name takes the top spot in a dynasty-focused ranking.

What connects Alberta’s biggest fortunes

The common thread is business ownership, not inherited wealth alone. The Southerns started with $4,000 and 15 trailers. Katz began with a $300,000 pharmacy franchise deal. The Mannix family started with horses and railway earthmoving work. Riddell brought geology to oil, while Werklund found opportunity in industrial waste.

Each fortune also relied on a different bet. The Shaws owned the wire into the home. Edwards bought assets during downturns. The Markins tied energy success to health philanthropy. The Mannixes built, held, divided, and sold businesses across generations.

Alberta’s wealth can be loud, especially when it is attached to hockey teams, arenas, ski resorts, and major public companies. Yet the province’s most enduring fortunes often came from patient ownership and businesses that solved an unglamorous problem.
