What employee burnout costs an employer in Canada
Employee burnout costs a Canadian employer in absence, departures and reduced output. No single figure covers all three, so build a range from your own numbers.
Employee burnout costs a Canadian employer money in three places: salary paid for days not worked, the cost of replacing people who leave, and reduced output from people who stay. No published figure covers all three for one organization, so the useful number is a range built from your own headcount, salaries and absence data.
The national picture sets the scale. A 2026 report from CSA Group, with Heal-3 and the Institute for Work & Health, put the yearly economic cost of poor mental health in Canada at about CAD 180 billion, and CSA Group says employers absorb more than CAD 110 billion of it. That figure covers mental health broadly, not burnout alone, which is why the rest of this post is about how to size your own share.
What counts as employee burnout?
The World Health Organization defines burn-out as a syndrome resulting from chronic workplace stress that has not been successfully managed, marked by exhaustion, growing mental distance from the job, and reduced professional efficacy. It classes burn-out as an occupational phenomenon and states that it is not a medical condition.
That definition has a practical consequence for a finance conversation. Burnout is rarely a line in a claims file. It shows up as absence, as departures and as output that falls without anyone leaving, and each of those has other causes too. Any cost estimate has to say which of those it is counting.
How much does employee burnout cost an employer in Canada?
There is no single published cost of employee burnout for one Canadian organization, but three sources give the shape of it. Nationally, the Institute for Work & Health's analysis within the CSA Group report counts roughly CAD 17 billion of lost productivity a year from depression, bipolar disorder, anxiety disorders and substance use, of which CAD 12.5 billion is presenteeism and CAD 2.88 billion absenteeism. The Mental Health Commission of Canada, using 2011 data, put the cost to business of absenteeism, presenteeism and turnover from mental health problems at more than CAD 6 billion that year, and noted that its data may be out of date. For one person leaving, Gallup's often-cited estimate is that replacement can cost between half and two times the employee's annual salary. Gallup's estimate is American, published in 2019 and based on 2017 US turnover data, and it calls the range conservative.
None of these isolates burnout, and none is yours. Take a team of 100 at an average salary of CAD 70,000 with ten departures in a year. Replacement alone, at Gallup's range, is CAD 350,000 to CAD 1.4 million. That is arithmetic on assumed numbers, not a finding. The calculator below does the same sum with yours.

Your headcount, salaries and absence data give a yearly cost range, with every assumption shown. Enter your headcount, average salary and, if you know them, absence days and departures. The result is a range, with the assumptions beside it.

Why is absence a late signal of burnout?
Absence is the part of the cost that shows in the payroll report. In the national estimate above, presenteeism, people at work with reduced output, is more than four times the cost of absenteeism, CAD 12.5 billion against CAD 2.88 billion.
The workforce data point the same way. In April 2023, Statistics Canada found that 21.2% of employed Canadians, about 4.1 million people, reported high or very high work-related stress, and heavy workloads were the most common cause. If your only measure is the days people are away, you are reading the end of the process.
How do you make the case for burnout prevention to a CFO?
Bring one range, with its assumptions on the same page, and separate what you can count from what you cannot. You can count absence days and departures. You cannot yet count reduced output at work, and a CFO will trust the number more if you say so.
Then ask for something bounded. Pick one population, measure it before you change anything, make one change, and measure again at about ninety days with the same instrument. That is a decision a finance lead can say yes to, because it ends in a comparison rather than a promise. Programs like this are designed to help, and measuring twice tells you whether the change was worth scaling.
What should HR measure before spending on burnout?
Measure the demands, not only the outcomes. Absence and departures are outcomes. OHA's Five Loads framework separates the demands behind them into decisional, cognitive, emotional, relational and administrative load, because the response to each is different. A team losing time to approval queues needs process work. A team absorbing other people's distress needs something else.
In Québec, the CNESST lists high workload, or overload, as a risk factor present in every workplace, which gives HR teams there an additional reason to look at it directly. Wherever you are, the order is the same: name the load, change one thing, measure again.
A baseline also changes the conversation inside the organization. When a leader says their team is stretched, HR can ask which load, how it reads against the other teams, and what would be different in ninety days if the change worked. That turns a general concern into a question with an answer, and it gives you something to put beside the absence report instead of waiting for it to move.
What OHA does about this
OHA's Capacity Diagnostic measures the five loads across your teams, shows which one concentrates where, and measures them again at 90 days with the same instrument. It is built to give HR a baseline and a comparison the CFO can read, ahead of the absence report. See how OHA approaches burnout prevention for HR teams.
