Department of Public Works and Government Services (PSPC) - *Canada, Gatineau, QC

This appears to be an open Innovative Solutions Canada (ISC) challenge sponsored by Innovation, Science and Economic Development Canada (ISED), with PSPC listed as the buyer. The government is seeking a novel magnetometer—quantum, classical, or hybrid—with improved sensitivity, specificity, size, weight, power consumption, cost, or ability to operate across multiple environments. The proposed system would likely need to combine hardware and software and detect very weak magnetic signals for defence, security, medical, or commercial applications. The challenge identifies technologies such as SQUID, SQIF, NV-diamond, Rydberg-atom, and SERF sensors as possible approaches, but does not appear to limit submissions to these technologies. Key mandatory outcomes described include: - Detect magnetic anomalies at distances of at least 2 metres, with relative error below 10%. - Provide azimuth and inclination readings within ±5 degrees. - Achieve at least 500 picotesla sensitivity in a prototype, with a target of 10 femtotesla. - Distinguish a target signal from background magnetic noise. - Detect and classify three specific Steel 1018 ferromagnetic targets from at least 10 metres through free space, with a 95% true-positive rate for detection and classification. - Roughly characterize the source, such as distinguishing a point source from a larger object, to within approximately ±5 centimetres. - Provide sensing, ranging, directional readings, and displayed results within 200 milliseconds. The listed opening date is October 30, 2026, and the closing date is November 27, 2026 at 2:00 p.m. Eastern Time. The challenge is located in Canada, with Gatineau, Quebec shown in the listing. The funding mechanism is identified as a contract. Applications appear to be submitted through the ISC challenge process rather than through a conventional price-based tender. The notice directs proponents to review ISC Call for Proposals 004 (EN578-24ISC4) and then submit through the ISED challenge webpage. The description provided is truncated, so additional technical, eligibility, intellectual-property, security, testing, and proposal requirements may apply. A Canadian business developing advanced magnetometry, sensing, signal processing, or related defence and security systems may find this potentially relevant. However, this summary does not establish eligibility or compliance. Review the complete official challenge notice and Call for Proposals, confirm the submission method and deadlines, and verify every mandatory requirement with the official sources before submitting a proposal.
