Asbestos got into Canadian homes because it worked. It would not burn, it held heat, it muffled sound and it cost very little. For most of the twentieth century that made it an obvious choice for builders, and it went into everything from roof shingles to furnace insulation. The bill came later, in the form of a health hazard that is still sitting inside older houses today.
This is not ancient history. The material was never removed from the houses it was built into, so the question for any homeowner is simple: was my house built during the years when asbestos was standard? At Mold Removal Winnipeg, we answer that question most weeks for owners of older Winnipeg homes, usually just before a renovation starts.
How Asbestos Became a Building Standard
People have used asbestos for its fire resistance for thousands of years, in lamp wicks and in cloth. Industrial use is much newer. It began in the late nineteenth century and grew quickly through the early and middle decades of the twentieth, alongside the construction boom that followed the wars.
Builders had a cheap mineral that resisted fire, insulated well and absorbed sound. Manufacturers could mix it into almost anything and make the product stronger. Nothing else on the market did all of that at the same price, so asbestos became routine rather than special.
Canada’s Part in the Story
Canada was one of the world’s major asbestos producers for more than a century. The mines were in Quebec, and the product was chrysotile, the curly white fibre that makes up the large majority of asbestos ever used. Canadian builders had a domestic supply, and Canadian homes reflect that. Our post on the different types of asbestos explains how chrysotile differs from the rest.
What It Went Into
Asbestos was not confined to one part of the house. Common products included:
- Cement products, including roofing shingles, siding and pipes
- Wall, attic and pipe insulation, plus wrapping around heating systems
- Vinyl floor tiles, sheet flooring and the adhesive under them
- Textured coatings, popcorn ceilings and some paints
- Duct insulation and fireproofing in furnace rooms
Because it was blended into ordinary materials, asbestos disappeared into the structure of the building. Nothing looks unusual, which is the reason a visual check settles nothing.
That is why testing exists. If your home has any of these materials, call Mold Removal Winnipeg at (204) 789-1514 before you start a project.
What Changed
Evidence of harm built up over decades. Workers who breathed the fibres developed serious lung disease, and the illnesses appeared long after the exposure, often many years later. Long-term exposure is linked to lung cancer, mesothelioma and asbestosis. The same durability that made asbestos useful in a wall makes the fibres very hard for the body to clear.
As the evidence became undeniable, governments moved from ignoring the risk, to restricting use, to prohibiting it. Asbestos is no longer used in new construction materials in Canada, and work that disturbs existing material is now regulated. Requirements change and vary by province and by job, so treat a licensed abatement contractor as your source for the rules that apply to your project.
Which Building Years Carry Risk
Construction year is the fastest way to judge the odds in your own house. As a general guide:
- Built before the 1980s: a very high likelihood of asbestos-containing materials
- Built between the 1980s and the 1990s: still a real likelihood, since older stock stayed in use
- Built after the 1990s: unlikely to contain asbestos materials
Use those as odds, not conclusions. A newer house can hold old material brought in during a renovation, and a very old house may have been stripped years ago. Only testing tells you what is actually there.
If your home falls into the first two groups and you are planning work, call Mold Removal Winnipeg at (204) 789-1514 and have the materials checked first.
Why Winnipeg Homes Still Carry It
Many Winnipeg neighbourhoods were built well before asbestos was phased out, and those houses are still lived in and still being renovated. Our winters keep furnaces and boilers working hard, which means decades of heat cycling on the insulation around them. Spring water in a basement soaks pipe wrap, ceiling tile and fibreboard, and those materials break down as they dry. Age plus moisture plus heat is how intact material turns into damaged material.
What This Means for You Today
Asbestos that is intact, sealed and undisturbed is often left in place and monitored. Damaged material, or material in the path of a renovation, is a different situation. Either way, the first step is the same. Only a laboratory can confirm asbestos, and the material should never be removed by the homeowner. A trained technician takes the sample safely, and the lab result drives the plan. Our post on where asbestos is found in a house shows where to start looking, and our asbestos removal and abatement page explains how safe removal is done.
