If your Regina or Saskatoon home was built between approximately 1965 and 1978, there is a significant chance it contains aluminum branch circuit wiring. During that period, a copper shortage drove builders to use aluminum as a lower-cost alternative. It conducted electricity fine — but created a long-term safety problem that tens of thousands of Saskatchewan homeowners are still dealing with today.
Pre-1940s homes in Saskatchewan face a different but equally serious legacy issue: knob-and-tube wiring, an early electrical system that is now well past its service life. Understanding what you have and what the risks are is the first step toward protecting your family.
Aluminum wiring expands and contracts more than copper does with temperature changes. Over time, this movement causes wire connections at outlets, switches, and junction boxes to loosen. Loose connections create resistance; resistance creates heat. In the worst cases, this heat ignites the surrounding insulation and framing, causing house fires that can start inside walls with no visible warning.
Homes with aluminum wiring are approximately 55 times more likely to have one or more wire connections reach fire-hazard conditions than homes wired with copper, according to research cited by the U.S. Consumer Product Safety Commission. While Canadian and American building standards differ, the underlying physics of aluminum oxidation and thermal expansion are the same.
Aluminum wiring was most commonly installed in homes built between 1965 and 1978. In Regina and Saskatoon, this corresponds to significant residential expansion periods — many established neighbourhoods like College Park, Lakeview, Confederation Park, and similar suburbs of that era were built during this window.
Any of these signs in an older home warrant a licensed electrical inspection immediately.
This is where the issue becomes financially consequential for many Saskatchewan homeowners. Many insurance companies in Canada either decline to insure homes with aluminum wiring or charge substantially higher premiums. When you go to renew or shop your home insurance, failing to disclose aluminum wiring — or having it discovered after a claim — can result in denied coverage. Several Saskatchewan homeowners have found this out the hard way at claim time.
If you are buying a home in Regina or Saskatoon and the inspection reveals aluminum wiring, verify with your insurance broker before closing that the home is insurable at a rate you're comfortable with.
Knob-and-tube wiring was the standard method in homes built before approximately 1940. It uses individual hot and neutral conductors separated by air (no ground wire), routed through ceramic knobs stapled to framing and through ceramic tubes where wires pass through framing members. The system has been out of code compliance for new work for decades, but it was never retroactively banned, so many older homes still have it.
For aluminum wiring, the gold standard is a full copper rewire — replacing all aluminum branch circuit wiring with copper. This is disruptive and expensive (typically $8,000–$20,000+ depending on home size) but eliminates the hazard entirely. A less disruptive option is "pigtailing" — connecting short copper wires to the ends of existing aluminum wires at every device using specially rated connectors (CO/ALR rated devices and purple wire nuts designed for aluminum). When done correctly by a licensed electrician, this is accepted by the Canadian Electrical Code as a safe remediation.
For knob-and-tube, partial replacement of the most hazardous circuits combined with GFCI protection and proper documentation for insurers is sometimes practical for older homes where full rewiring would require major structural disruption.
Regardless of wiring type, Saskatchewan's wet spring season and moisture-prone basements make GFCI (Ground Fault Circuit Interrupter) outlets critical in kitchens, bathrooms, garages, basements, and exterior outlets. Spring flooding and snowmelt regularly find their way into Saskatchewan basements — GFCI protection can prevent electrocution in a flooded space.
Hey Fix It Pro works with licensed electricians across Regina and Saskatoon and can help coordinate inspections and remediation for aluminum wiring and knob-and-tube concerns.
