Medical providers rely on diagnostic imaging to identify, evaluate, and track a broad spectrum of medical conditions. While the Ontario Ministry of Health emphasizes that the province completes more scans than ever, a recent independent report by the Canadian Institute for Health Information (CIHI) confirms that patients still experience delays that routinely exceed recommended targets.
Over the past twenty years, the average age of imaging equipment in Canada has increased, with at least one-third of equipment now being over ten years old. Funding for renewed equipment is urgently needed; with that comes the need for infrastructure to house it.
While traditional construction follows a linear sequence where one event must be completed before another, modular construction allows for work to progress in parallel workflows. Cassette® fabrication occurs off-site in a factory-controlled environment, meaning site preparation — laying foundations, utilities, and building the physical shell — begins simultaneously rather than sequentially, substantially reducing the pressure point of diagnostic imaging wait times.
Faster deployment means faster patient access
There is a clear timeline difference between traditional building and prefabrication: a conventional on-site expansion of a diagnostic imaging department can take an average of 24-36 months to construct. In contrast, prefabricated MRI/CT Cassettes arrive substantially complete, compressing that timeline to 12-16 months for site prep, placement and commissioning. Every month saved translates to reduced wait times; more patients screened means potentially, more lives saved.

Cost Vs Quality Vs Time
Definitively, modular Cassette infrastructure is breaking the construction triangle of cost vs quality vs time. On-site work in hospital settings is often restricted to small windows to reduce impact on clinical operations, which can double or triple construction timelines. With modular construction, there is minimal disruption to active clinical environments — a critical factor for hospitals facing prolonged construction adjacent to patient care areas.
As well, weather conditions frequently stall traditional construction delaying exterior site preparation for months out of the year. Cassette fabrication happens entirely in a factory-controlled environment, improving labour efficiency, quality control, and reducing cost overruns. The site logistics that consistently plague conventional healthcare construction are eradicated. Instead, predictable delivery dates enable coordinated equipment procurement, vendor scheduling, and clinical planning with far less risk of cascading delays.
No Compromise on Code
Despite the speed at which modular construction is built, the units never compromise in standards. Neither temporary or trailer-grade, prefabricated Cassettes are engineered to meet the same CSA Z8000, National Building Code, and provincial healthcare facility standards as conventional construction. They are also fully compliant with RF shielding performance requirements, magnetic siting criteria, HVAC/pressurization standards, and infection prevention and control (IPAC) design guidelines.

Quality assurance happens in a controlled environment with repeatable processes, including RF shielding installation and testing before the unit ever reaches the site. Once the site preparation is complete, the prefabricated modular Cassettes are shipped to the site and crane-assembled, often complete with medical gas lines, electrical wiring, and plumbing already pressure-tested and certified in the factory, cutting down the final operational readiness phase by several months.
Once in place, the modular Cassettes provide the same stability and longevity as stick-built construction and have the same lifecycle expectations with a 50+ year lifespan.
However, the integration of a prefabricated diagnostic suite is entirely dependent on the speed of government procurement — a process which often exceeds the physical construction timeline itself. A suite can be delivered in months, while the lengthy administrative procurement processes undermine the modular’s core speed advantage. This inefficiency leads to financial waste, as inflation and equipment costs compound during the prolonged waiting periods.
Meanwhile, patients absorb the cost of administrative timelines through longer diagnostic wait lists and deferred diagnoses.
Once funding is approved, SDI Canada can react quickly. Their prefabricated modular Cassette solution can be designed, built and delivered in as little as 6 months, installed in 2 days, and ready to receive patients within 5 weeks.
Consider this: In 2024, Brockville General Hospital saw its first patient scanned in a new MRI suite just 12 months after the construction contract was awarded. Similarly, St. Joseph’s Hospital in Estevan, SK, saw a high-spec MRI Cassette delivered within 9 months of starting construction.
The Sioux Lookout Meno Ya Win Health Centre in Northern Ontario — where patients previously had to travel to either Thunder Bay or Winnipeg to receive care — established an MRI department in 2026 within 13 months of the contract being awarded. And at the Upper River Valley Hospital in Waterville, NB, a high spec MRI Cassette was delivered to the site within 9 months of construction beginning.
These are not outliers; this is the new benchmark for diagnostic infrastructure in Canada.
Founded in 2003, SDI Canada is the Canadian leader in the implementation of MRI and biomedical equipment, the design and construction of medical infrastructures and the distribution of specialized accessories. To learn more, visit www.sdicanada.ca or email [email protected].
