Source-derived summary

The Principal Group was a group of interrelated Canadian financial companies that collapsed in 1987, resulting in losses to an estimated 67,000 people. Losses were recovered in part through provincial governments paying compensation, based on findings as to deficiencies in regulatory oversight.

History

The Principal Group was primarily three companies: First Investors Corporation, Associated Investors of Canada and Principal Savings and Trust Corporation. First Investors Corporation was established by Donald Cormie in 1954. The company was initially based in Edmonton, Alberta. The company sold investment contracts, which were contracts by which investors remitted monthly amounts to First Investors Corporation, in return for a promised future redemption amount, plus interest. In 1959, First Investors opened offices in Nova Scotia, New Brunswick and Newfoundland. At the same time, it also opened offices in Washington, Oregon and Colorado as Principal Investors, since the name First Investors was owned in the United States by another party. Associated Investors of Canada was acquired in 1962.

The companies were subject to Alberta Securities Commission regulation and also required licences to sell investment contracts.

Editorial analysis

Why this record matters

The phrase “defunct group of Canadian financial companies” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 16, 2026. The linked authority identifier is Q30715339. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1987, 1954, 1959 and 1962.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
