Building a new life in Canada can come with unexpected changes, including developing allergies that were never an issue back home.

In fact, research shows that the longer newcomers live in Canada, the more likely they are to develop allergies.

A study in an immunology journal found that about 14 per cent of recent newcomers to Canada reported non-food allergies, but that number climbs to roughly 24 for those with a decade or more here. Researchers believe a mix of environmental and lifestyle changes may be driving this shift. These can include differences in air quality, diet, sanitation and how the immune system adapts to a new environment.

“We’re seeing a pattern suggesting that the Canadian environment plays a significant role in allergy development,” says Dr. Harold Kim, an allergist and immunologist. “If you’re someone who hasn’t experienced allergies before, it’s important to recognize the signs early and speak with a doctor if something feels off.”

Signs to watch for: Allergy symptoms can range from sneezing and itchy eyes during allergy season to hives, swelling, or serious reactions after eating certain foods. In some cases, reactions can happen very quickly. Severe and potentially life-threatening reactions, known as anaphylaxis, require immediate treatment with epiephrine, such as from an EpiPen.

What to do if symptoms appear: If you or a family member develops new or worsening symptoms after arriving in Canada, don’t ignore them. A family doctor can help assess your symptoms or refer you to an allergist. Getting a diagnosis can help you manage your condition and be prepared if a serious reaction occurs.
