You’ve probably heard people talk about "white gold" in the context of the Canadian prairies. They aren't talking about snow. They're talking about potash, that pinkish, salty mineral that basically keeps the global food supply from collapsing. For decades, the Potash Corporation of Saskatchewan Inc—or PotashCorp, as everyone actually called it—was the undisputed heavyweight champion of this industry. It wasn't just a company; it was a massive political and economic engine that dictated how much farmers from Brazil to China paid to keep their soil fertile.
But then, it just... vanished. Well, not vanished, but it transformed.
If you look for their ticker on the TSX today, you won't find it. In 2018, a massive "merger of equals" with Agrium created a new giant called Nutrien. It was the end of an era. Honestly, it’s a bit weird to think about how much power one company in Saskatoon held over the world's dinner plates. Understanding what happened to PotashCorp isn't just a history lesson in Canadian mining; it’s a masterclass in how global commodities markets actually work when the stakes are literally "will people have enough to eat?"
From Crown Corporation to Global Predator
The origins of Potash Corporation of Saskatchewan Inc are kinda messy. Back in the 70s, the Saskatchewan government under Allan Blakeney got tired of private companies reaping all the rewards from the province's massive potash reserves. They decided to nationalize a chunk of the industry. It was a bold, controversial move. At the time, critics called it a socialist overreach. Supporters called it taking back their heritage.
By 1989, the political winds shifted. The province took the company public, and that’s when the real growth started. Under the leadership of CEOs like Chuck Childers and later Bill Doyle, PotashCorp became a predatory, profit-seeking machine.
They didn't just dig holes in the ground. They understood leverage.
Because Saskatchewan holds nearly half of the world's known potash reserves, PotashCorp was able to lead a marketing group called Canpotex. Think of it like OPEC, but for fertilizer. By controlling how much potash hit the market, they could keep prices stable—and high. It was a brilliant strategy until it wasn't.

The 2010 BHP Takeover Battle That Changed Everything
If you want to understand the soul of this company, you have to look at 2010. BHP Billiton, the Australian mining behemoth, launched a hostile $40 billion bid to buy PotashCorp. It was the kind of corporate drama that usually stays in boardroom basements, but this became a national identity crisis in Canada.
People in Saskatchewan were furious. The "Potash is Ours" sentiment roared back to life.
Eventually, the federal government stepped in. They used the "Net Benefit" test under the Investment Canada Act to block the deal. It’s incredibly rare for Canada to block a takeover of this scale. It proved that Potash Corporation of Saskatchewan Inc was considered a "strategic asset." Basically, the government decided that letting an Australian company control the world’s fertilizer supply from a Saskatoon office was a bridge too far.
Why the Potash Market Broke
Economics 101 says that when supply goes up, prices go down. Simple, right? But the potash market was a weird, protected bubble for a long time.
Then came 2013.
A Russian company called Uralkali decided to break up its marketing partnership with Belarus. They basically said, "We’re going to produce as much as we want and sell it for whatever we can get." This shattered the "price over volume" model that PotashCorp had relied on for years. Potash prices plummeted. The industry went into a tailspin.

This is why the merger with Agrium happened. PotashCorp was a "pure play" miner. They were great at getting stuff out of the ground, but they were vulnerable to price swings. Agrium, on the other hand, had a massive retail network—they sold seeds and chemicals directly to farmers.
By merging, they created Nutrien. It was a defensive move. It was about survival.
The Reality of Mining in Saskatchewan
Mining potash isn't like mining gold. You aren't looking for a tiny vein in a rock. You're looking at massive, prehistoric evaporated sea beds located about a kilometer underground.
The scale is staggering.
At mines like Lanigan or Rocanville, the machines are the size of houses. It’s a high-capital, high-risk game. When you build a potash mine, you aren't thinking about next quarter; you're thinking about the next fifty years. This is why Potash Corporation of Saskatchewan Inc always had a weird relationship with its shareholders. Investors wanted quick returns, but the geology demanded patience.
What Most People Get Wrong About Potash
There is a common misconception that potash is just another commodity like oil or copper. It isn't.

You can live without a new iPhone. You can even live with less oil if you have an EV. You cannot grow food at scale without potassium. It is one of the three essential nutrients in fertilizer (N-P-K: Nitrogen, Phosphorus, and Potassium).
When PotashCorp was at its peak, it wasn't just selling a product; it was selling food security. That’s why the company was so profitable for so long. They had a moat that was literally miles wide and a kilometer deep.
- Environmental impact: Potash mining is generally "cleaner" than coal or oil sands, but it leaves behind massive salt tailings piles. Dealing with these is a multi-generational challenge that Nutrien has inherited.
- Geopolitics: Most of the world's potash is in Canada, Russia, and Belarus. If you look at the news lately, you can see why Canadian potash is suddenly the most popular kid at the dance again.
- Employment: For decades, PotashCorp was the employer in Saskatchewan. High-paying, stable, union jobs. That legacy still exists, even if the name on the hard hat has changed.
Actionable Insights for Investors and Observers
If you’re looking at the fertilizer space now, don't go looking for Potash Corporation of Saskatchewan Inc on the stock exchange. It's gone. But the lessons from its rise and fall are still incredibly relevant.
First, watch the "Price vs. Volume" battle. The industry is still trying to decide if it wants to be a disciplined cartel or a cutthroat free market. Every time a new mine opens in the BHP Jansen project, the ghosts of PotashCorp's old strategy start rattling their chains.
Second, understand that the retail side is where the stability is. The reason the PotashCorp/Agrium merger worked is that it balanced the volatility of mining with the steady income of selling bags of fertilizer to farmers in Iowa.
Finally, keep an eye on geopolitical stability. With sanctions on Russia and Belarus, the Saskatchewan mines—the ones once owned by PotashCorp—are basically the only reliable source of potash for the Western world right now.
To stay ahead of this market, you need to track:
- Crop prices: If corn and soy prices are high, farmers spend more on fertilizer.
- Natural gas costs: Nitrogen fertilizer (the "N" in NPK) is made from gas, which affects the overall "fertilizer basket" price.
- Global inventory levels: Watch the port inventories in Brazil and China. They tell you more about future potash prices than any corporate press release ever will.
The era of Potash Corporation of Saskatchewan Inc might be over, but the dirt beneath our feet in Saskatchewan is still the most valuable real estate in the global food chain. Understanding that history is the only way to make sense of where the industry is heading next.
