FlexPak Leak Detectors Inc.

FlexPak Leak Detectors Inc. is proudly headquartered right here in St. Catharines, Ontario. Since our founding, we’ve combined Canadian ingenuity with world-class engineering to design and build reliable, precision leak-testing equipment for a wide range of industries—from food and beverage to medical and industrial packaging. Our entire research, development, and assembly process takes place in our St. Catharines facility, ensuring tight quality control and rapid response to customer needs.

At FlexPak, we specialize in bubble-emission leak detection technology, which not only confirms the presence of a seal failure but pinpoints its exact location. Every tank, controller, and accessory is crafted to the highest standards of durability and accuracy. By keeping production local, we maintain shorter lead times, rigorous testing protocols, and a highly skilled workforce dedicated to continuous improvement and customer support.

We're honoured to work with industry giants like Costco Wholesale Foods, Lactalis, Kroger, Cargill, Nestlé, and Mars—while delivering the same precision and partnership to up-and-coming brands. So no matter your size, we're happy to help!

As an Ontario-made manufacturer, we’re committed to our community and the environment. We source materials from local suppliers wherever possible, optimize our energy use in production, and support Ontario’s economy by investing in training, jobs, and partnerships with fellow businesses. When you choose FlexPak, you’re not just getting top-of-the-line leak-testing equipment—you’re supporting Ontario families, innovation, and sustainable manufacturing.
