Elrex Manufacturers’ History

Elrex was officially established in May 1963 by partners Sidney Albert Semper and Bill Rex Semper. Originally intended to be named ALREX, a notarial error led to the registration of ELREX, an unexpected change that became the name we’ve proudly carried forward ever since.
From its early years, Elrex developed into an established Canadian manufacturer specializing in custom plastic parts and components.

Over his 23 years at Elrex, Anthony Bosse played a key role in modernizing operations by introducing new plastic fabrication methods, equipment, and software. His leadership and focus on quality manufacturing and growth led him to take on the role of President following the retirement of his predecessor.

Elrex Manufacturers Inc. now operates out of a modern, upgraded facility in Ottawa, equipped with advanced machinery, modern manufacturing software, and expanded production capacity for precision plastic parts and industrial components.
Under the leadership of President Michael Lambersky, Elrex continues to evolve as an established Ottawa plastic manufacturing company. With over 15 years of experience in component manufacturing and telecommunications through The ID Group, Michael brings a strong focus on innovation, efficiency, and growth to the next chapter of Elrex.
