You probably haven't heard the name Potash Corp of Saskatchewan Inc mentioned in a stock ticker for a while. There’s a good reason for that. It doesn't technically exist anymore, at least not in the way it did when it was the undisputed heavyweight champion of the fertilizer world.
Back in the day, if you lived in Saskatoon or followed the TSX, this company was basically the center of the universe. It was a massive, sprawling entity that controlled a huge chunk of the global nutrient market. People called it PotashCorp. Simple. Powerful. But then 2018 happened, and the company pulled off a "merger of equals" with Agrium to create Nutrien.
Honestly, the story of how a provincial Crown corporation turned into a global private powerhouse—and then vanished into a new corporate identity—is a wild ride of Canadian politics, hostile takeover bids, and the literal dirt that keeps the world from starving.
The Weird History of Potash Corp of Saskatchewan Inc
It started as a government project. In 1975, the Saskatchewan government was tired of private companies mining the province's "pink gold" and shipping the profits elsewhere. So, they created a Crown corporation. They actually bought out several private mines to make it happen. It was controversial. Some people loved the idea of provincial ownership; others thought it was a socialist nightmare.
By 1989, the winds changed. The government decided to privatize.
The transition from a state-owned entity to a publicly traded beast was aggressive. They started snapping up assets everywhere. They didn't just stay in Canada; they bought into companies in Chile (SQM), Israel (ICL), and Jordan (Arab Potash Company). They became the largest producer of potash in the world. For a few decades, they were the "Saudi Arabia of Fertilizer."
Why Potash Actually Matters
Potash is just potassium, mostly. It’s mined from ancient evaporated sea beds buried miles underground. If you don't have it, crops don't grow well. They get "thirsty" and "weak." Farmers need it to improve water retention and yield.

Saskatchewan has the best deposits on Earth. Period. The Lanigan and Rocanville mines are legendary in the industry for their scale. Potash Corp of Saskatchewan Inc knew this. They leveraged that geological luck into a massive market influence.
The BHP Takeover That Shook Canada
If you want to understand why this company was so important, you have to look at 2010.
BHP Billiton, the Australian mining giant, decided they wanted in. They launched a hostile takeover bid for $38.6 billion. It was huge. It was the kind of money that makes people lose their minds. The CEO at the time, Bill Doyle, was a classic "big personality" executive who fought it tooth and nail.
The Canadian federal government actually stepped in. They used the "Investment Canada Act" to block the deal, claiming it didn't provide a "net benefit" to the country. It was a rare move. It showed that Potash Corp of Saskatchewan Inc wasn't just another company; it was a strategic national asset.
It's weird to think about now, but for a few months in 2010, the fate of a fertilizer company in the prairies was the biggest news story in the global financial world.
The Nutrien Era and the Identity Shift
By 2016, the fertilizer market was kind of a mess. Prices had tanked from their 2008 highs of nearly $900 a ton down to the $200 range. The industry was bloated.

PotashCorp had the mines (the "upstream" stuff). Agrium had the retail stores (the "downstream" stuff). It was a logical marriage. They announced the merger, and by January 1, 2018, the ticker symbol POT was gone.
Nutrien is now the name on the building.
Does it matter? To an investor, maybe not. The dividends still flow. But for the identity of Saskatchewan, it felt like the end of an era. The headquarters stayed in Saskatoon—mostly—but the company became a different kind of animal. It became less about the specific mineral and more about the "full acre solution."
The Realities of Global Supply Chains
Post-2022, the world realized how fragile fertilizer supplies are. When Russia and Belarus—two other massive potash producers—faced sanctions and logistics issues, everyone looked back at the old Potash Corp of Saskatchewan Inc assets.
The mines in Saskatchewan are some of the only places on the planet that can actually ramp up production to fill a global void. This is high-stakes stuff. We're talking about global food security. If the mines in Allan or Cory stop working, bread gets more expensive in Cairo and Chicago.
What Most People Get Wrong About the Company
People think it was just about mining.

In reality, the company was a master of logistics and cartels. For years, they operated through Canpotex, a joint marketing entity. It was basically the OPEC of potash. They controlled the supply to keep prices stable. When that system started to crack—especially when the Russian producer Uralkali broke away from its own partnership in 2013—the "old way" of doing business died.
Potash Corp of Saskatchewan Inc had to learn to be lean. They had to close high-cost mines, like the one in New Brunswick (Picadilly), which was a huge blow to that local economy. It wasn't all growth and glory; there were some really tough, cold-blooded business decisions made to keep the company afloat during the lean years.
Practical Insights for the Modern Investor or Observer
If you're looking at the legacy of this company today, don't look for the old name. Look at the infrastructure.
- Check the Ticker: If you want to own a piece of what used to be PotashCorp, you're buying NTR (Nutrien) on the TSX or NYSE.
- Watch the Geopolitics: Potash is a political commodity. When Eastern Europe is in turmoil, the value of Canadian potash skyrockets.
- Understand the Cost Curve: Saskatchewan mines are deep, but they are high-quality. The "cash cost" to get a ton of potash out of the ground in a place like the Rocanville mine is significantly lower than almost anywhere else. That is their "moat."
- Inventory Matters: Unlike gold or oil, potash is seasonal. Farmers buy in the spring and fall. If the weather is bad, the company's quarter will be bad. It's that simple.
The legacy of Potash Corp of Saskatchewan Inc is still buried in the ground. It’s in the miles of tunnels beneath the prairie wheat fields. While the corporate letterhead has changed, the fundamental reality remains: the world needs that pink salt, and Saskatchewan is still the best place to get it.
To stay ahead of this sector, keep a close eye on the "Big Three" nutrient prices—nitrogen, phosphate, and potash—and don't ignore the rail lines. In Canada, if the trains aren't moving, the potash isn't selling. That’s the real-world bottleneck that matters more than any corporate rebranding.
Monitor the quarterly reports from Nutrien and Mosaic. These are the descendants of the potash boom. They carry the same risks and rewards that defined the original company for over forty years.
