Diabetes prevalence in Canada has shown a notable stabilization in recent years, according to new data, marking a contrast to global trends where the disease has doubled over the past three decades. A study published in The Lancet ahead of World Diabetes Day highlighted that while the prevalence of diabetes worldwide reached an alarming 14% in 2022, Canada’s rates have neither increased nor decreased significantly since 1990. This apparent stability might suggest progress, but experts caution that it masks underlying issues and warn against complacency, as diabetes remains a serious public health concern.
Between 2000 and 2021, the Government of Canada reported that 3.7 million Canadians were living with diabetes. At that time the prevalence of all types of diabetes was 8.7% among women and 10.1% among men, and 22.5% who met the diagnosis criteria for diabetes were unaware of their condition.
Despite these figures being lower than in many other countries, endocrinologist Jeremy Gilbert warns that diabetes is “still really an epidemic” in Canada, affecting one in 10 people.

The relative progress among women in Canada has been attributed to several factors. Women in Canada have lower obesity rates compared to those in countries like the United States, and biological factors such as estrogen may provide some protection against diabetes, particularly at younger ages. However, experts also note concerning trends, such as the rise in gestational diabetes during pregnancies, which could signal future health challenges. Lorraine Lipscombe, an endocrinologist at Women’s College Hospital in Toronto, emphasized that women under 50 are increasingly catching up to men in terms of diabetes prevalence, an alarming development.
The stabilization of diabetes rates in Canada could reflect improved screening and awareness. “One piece of good news is that more people are likely being screened and tested for diabetes than before,” said Lipscombe. Yet, experts also point to systemic barriers that prevent further progress. Diet and lifestyle changes, while known to be critical for diabetes prevention, remain difficult for many Canadians to implement.
“We tell people to eat vegetables and proteins, but those are the most expensive foods,” said Gilbert, highlighting how the high cost of healthy eating disproportionately affects vulnerable populations.
Canada’s aging population is another significant factor contributing to diabetes rates. With advancing age, the likelihood of developing diabetes increases, driven by both biological factors and lifestyle risks, such as sedentary behavior. Lipscombe noted that while the Lancet study provides valuable insights, it may underestimate the true prevalence of diabetes in Canada due to limitations in data collection methods.
Relevant to this topic, Global News did a feature for Diabetes Awareness Month -- Dr. Jeremy Gilbert discussed the growing prevalence, factors behind the rising numbers, and the role of continuous glucose monitoring technology like the Dexcom G7. He also shares patient success stories and highlights why it’s crucial to consult a doctor about potential symptoms.
Coming back to the Lancet article and on the treatment side, Canada has made significant strides. Along with countries like Mexico, Chile, and Costa Rica, Canada has seen substantial improvements in diabetes care over the past three decades. Approximately two-thirds of Canadians with diabetes aged 30 and older are now receiving treatment. The introduction of Canada’s new Pharmacare law is expected to further enhance access to medications, reducing disparities and improving health outcomes for patients nationwide.
“Canada’s universal healthcare system gives it an advantage over other countries when it comes to accessing care and recommending treatment for diabetes,” said Lipscombe.
Despite this progress, gaps in care remain, especially for vulnerable populations. The need for continued investment in education, affordable healthy food options, and community-based interventions remains pressing. While Canada’s stabilization of diabetes rates offers a glimmer of hope, it also underscores the need for sustained efforts to address the underlying drivers of this complex disease.

Diabetes may not be rising as quickly in Canada as in other nations, but the disease still poses a significant burden on individuals, families, and the healthcare system. Experts agree that achieving meaningful progress will require a combination of improved prevention strategies, enhanced screening efforts, and equitable access to treatment for all Canadians. As Gilbert aptly put it, “There’s raised knowledge and awareness, but still a lot of work to do on the implementation side of things.”
