The Canadian Drugs + Substances Strategy
The Government of Canada’s approach to substance use related harms and the overdose crisis
The increasing toxicity and unpredictability of the illegal drug supply means that anyone is at risk for an
overdose, whether they are trying drugs for the first time, or have been using drugs frequently. While anyone
is at risk of a drug overdose, some populations in Canada have been disproportionately impacted by the
crisis. Males accounted for the majority of apparent opioid toxicity deaths in Canada (70 to 75% since 2016).
People living with co-occurring health conditions are also at increased risk of an overdose, including those
with mental health conditions and chronic pain.
Approximately 20% of Canadians with a substance
use disorder (SUD) also have a co-occurring mental
health disorder. Meanwhile, up to 55% of people
who use drugs are also living with chronic pain.
Indigenous populations in Canada also face
an increased risk of overdose death and other
substance related harms. According to the First
Nations Health Authority, First Nations people
died of opioid toxicity deaths at 5.9 times the rate
of other residents in British Columbia in 2022; a
disproportionate impact on Indigenous populations
that has also been seen across other provinces and territories. Historical and intergenerational trauma,
including the impact of colonization, loss of traditional culture and language, and experiences with Indian
Residential Schools, have contributed significantly to the elevated risk of overdose death and broader
substance use related harms amongst Indigenous Peoples. Systemic racism arising from Canada’s colonial
history has also created inequities for African, Caribbean and Black populations, which has resulted in
higher rates of poverty, unemployment, and precarious housing among these populations, placing them
at greater risk of substance use harms.
In addition to the overdose crisis, Canada continues to see harms from other substances, such as tobacco
and alcohol. According to the Canadian Costs of Substance Use and Harms 2007–2020 report, substance
use and its related harms from all substances cost Canadians more than $49 billion and led to the loss
of nearly 74,000 lives or 200 lives per day in 2020. In 2020, tobacco use was the leading cause of substance
attributable deaths with 46,366 deaths in 2020, followed by alcohol use with 17,098 deaths and opioid use with
6,491 deaths (see Figure 2).
The harms related to substance use are not limited to the loss of lives alone, but also include increased costs
to our health care system, from hospitalizations, emergency visits and specialized treatment for substance
use disorders, which amounted to $13.4 billion in
2020. Substance use also has economic impacts due
to lost productivity from premature deaths and time
o work due to disability, which cost $22.4 billion in
2020. The enforcement of substance use laws cost
Canada’s criminal justice system $10.0 billion in 2020.
