The research group highlights four “sole-source or critical suppliers” among the 110 Canadian companies which have participated in the development or production of the F-35. Among these, Gastops, “a small firm headquartered in Ottawa, ON, is particularly of note.”

Gastops is the sole producer in the world of the oil monitoring and fan blade health sensors used in the F-35, which are key components in maintaining the reliability of the warplanes. The Aerospace Industries Association of Canada emphasizes that “this is technology that nobody else has.” The value of the contracts awarded to Gastops for the F-35 exceeds $100 million, according to the report.

The implication of these violations is that “companies supplying critical parts of F-35 aircraft to Israel, directly or indirectly, and particularly sole-source suppliers of these parts, are therefore complicit in crimes against humanity, war crimes, and other grave breaches of the Geneva Conventions.”
