How it started
History
PotashCorp was established by the government of Saskatchewan in 1975. In 1989 it became a publicly traded company as the government of Saskatchewan sold off some of its shares, selling the remaining shares in 1990.
Crown corporation
The Saskatchewan potash industry began in the 1950s and 1960s. The government saw it as a promising new field and granted large subsidies to the new projects, mainly by American companies. However, this led to overproduction and when a global potash glut began in the late 1960s the industry almost collapsed. The Liberal government of the province introduced an emergency plan setting up quotas and a price floor in 1969. This plan was popular among the companies, which could now charge monopoly prices. The NDP government that was elected in 1971 in Saskatchewan was dissatisfied with this plan as the huge profits went to the companies rather than the government, and it wasn't sustainable in the long term. In 1974 the government passed a new potash regulation scheme, that included a reserve tax. This plan was resisted by the potash producers, and its constitutionality was challenged. Thus in 1975 the provincial government established the Potash Corporation of Saskatchewan as a government crown corporation.
In November 1975 the province announced its intention to take part of the potash industry into public ownership. The government offered to negotiate with the producers, and many of them agreed to sell to the government. Over the next several years PCS bought mines around Saskatchewan, and eventually came to control 40% of domestic production. Public ownership drew the ire of the United States government, which criticised the provincial government for buying Americans' assets and creating a monopoly. In the 1980s the United States Department of Commerce accused the corporation of dumping and imposed massive duties on all potash imports to the United States.
