About Us
Contretron Inc. has been a trusted supplier of innovative test equipment for the Telecommunications, Technology, and Security industries since 2005.
We are a small, family-run company specializing in reliable, innovative solutions to today's TSCM (Technical Surveillance Counter Measures) challenges. Our areas of activity span the full spectrum of TSCM needs: the distribution of specialized TSCM equipment, professional sweep services, expert consulting and hands-on support, training offered in both English and French, and In-Place Monitoring System (IPMS) solutions for continuous surveillance protection. We pride ourselves on offering a range of high-quality products — including Faraday enclosures, thermal cameras, and RF detection equipment — backed by exceptional customer service. As Electronic Counter Surveillance specialists, we advise government agencies, law enforcement, and private industry across Canada on effective TSCM solutions for detecting known, unknown, illegal, or disruptive electronic eavesdropping devices, and for safeguarding sensitive information.
Since 2005, we have proudly served as the Canadian distributor for Research Electronics International (REI), and we remain the only factory-authorized reseller of REI products in Canada. REI specializes in designing and manufacturing ultra-high-quality electronic test equipment for TSCM applications. Their complete in-house line of electronic countermeasures products has become the industry standard for government agencies, law enforcement organizations, corporate security departments, and TSCM professionals worldwide. REI also operates the largest commercial TSCM training facility in the world, offering in-depth professional courses.
Contretron Inc. is based in Granby, Quebec, Canada.
Our Vision
At Contretron Inc., we envision a future where organizations across Canada — from government institutions to private enterprises — never have to question whether their conversations, data, and physical spaces are secure. We believe that trusted information deserves trusted protection, and we are committed to being the partner Canadians rely on to make that possible.
As threats to privacy and information security grow more sophisticated, our vision is to remain at the forefront of TSCM innovation — not simply by distributing the world's best countermeasure equipment, but by building lasting relationships grounded in expertise, integrity, and personalized service. We aim to be more than a supplier: we strive to be a trusted advisor and long-term partner to every client we serve, guiding them through evolving security challenges with clarity and confidence.
Rooted in our family values, we envision growing Contretron Inc. while never losing the qualities that define us — accessibility, responsiveness, and a genuine commitment to our clients' security. Through our continued partnership with Research Electronics International, our investment in bilingual training and education, and our dedication to continuous monitoring solutions like IPMS, we look toward a future where technical surveillance counter measures are not an afterthought, but a standard of excellence embraced across every sector we serve.
