CSA Group Report: Poor Mental Health Costs Canada $180B Yearly

TL;DR: Poor mental health costs Canada about $180 billion each year, with employers shouldering roughly $110 billion. Presenteeism—working while unwell—drives most productivity losses, amounting to $12.5 billion annually.

Context CSA Group’s Public Policy Centre released a modelling study that estimates the annual economic burden of poor mental health in Canada at $180 billion. The authors note the figure is likely conservative because of data gaps. If trends continue, costs could rise to nearly $600 billion by 2050, approaching one‑fifth of projected GDP.

Key Facts Employers absorb about $110 billion of the total, mainly through disability claims, benefits, wage replacement, accommodations and insurance premiums. Only about 14 % of employer‑related mental‑health spending goes to prevention such as training, psychological‑health‑and‑safety programs and employee‑assistance plans. Presenteeism accounts for roughly $12.5 billion a year and represents nearly 90 % of productivity‑related losses; the report also states it makes up about 80 % of all productivity losses. National survey data cited in the report show that nearly one in three Canadian workers say their job performance is directly affected by mental‑health challenges. The study is a descriptive modelling exercise, not an RCT, so it identifies associations rather than proving causation.

What It Means The findings shift the focus from absenteeism to presenteeism as the primary driver of economic loss, indicating that many employees are present but functioning below capacity. For employers, increasing preventive investment could reduce downstream costs tied to disability leave, turnover and legal expenses. Safety leaders are urged to ensure adequate mental‑health benefits, assess psychosocial hazards, and train managers to recognize strain and direct staff to resources. Policymakers may need to align mental‑health funding with physical‑health coverage and embed prevention into workplace standards. Over the next decade, tracking changes in prevention spending and presenteeism rates will be key to gauging progress.

What to watch next Monitor whether employer prevention spending rises above the current 14 % level and track any changes in reported presenteeism and disability‑claim trends over the next five years. Policy announcements on workplace mental‑health standards could signal shifts in employer behavior.
