History

The company was founded in 1987 by Daniel Brosseau and Peter Letko who met while working at the investment division of CN.

Letko Brosseau exited the ownership of WestJet in 2019, after Onex Corporation took the company private for $31 a share. It was once a significant investor in the ill-fated British construction firm Carillion.

In December, 2019, the firm rejected Jim Pattison's $16-a-share cash bid to acquire lumber company Canfor, saying the offer undervalued the company. Letko Brosseau held 4.8% of Canfor stock as of December, 2019.

Letko Brosseau has been a major shareholder of Air Transat for many years owning nearly 20% of the company, while currently owning 12%.

Editorial analysis

Why this record matters

The phrase “investment Fund” 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

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 29, 2026. The linked authority identifier is Q65051195. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021, 1987 and 2019.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
