Canadian Centre on Substance Use and Addiction

The COVID-19 pandemic has impacted the lives of all Canadians. The ongoing economic hardships, changes to our daily routines and separation from loved ones, among other stresses, have been linked to the worsening of mental health and an increase in substance use among many Canadians.

The Canadian Centre on Substance Use and Addiction (CCSA) and the Mental Health Commission of Canada (MHCC) have commissioned the Leger polling firm to produce a series of bimonthly surveys over a twelve-month period to explore the long-term impact of the COVID-19 pandemic on Canadians’ mental health and substance use. By tracking trends among the general population and priority populations, CCSA and MHCC aim to build on our understanding of the relationship between mental health and substance use during COVID-19 and better support Canadians through these challenging times.

Survey Results

Summary Report One, Baseline Survey (Time 1) and Survey 2 (Time 2)

Leger conducted a baseline survey of 2,502 Canadians between October 13 and November 2, 2020, and a second survey of 1,507 people between November 19 and December 2, 2020. Respondents reported more mental health symptoms and increased substance use since March 2020. People with a history of mental health or substance use concerns were disproportionately impacted by stresses related to the COVID-19 pandemic.

Up to one in two individuals with an existing substance use disorder reported having moderately severe to severe symptoms of depression since March 2020. Around one third of those surveyed who drink alcohol reported drinking more since the start of the pandemic. This increase was greater among respondents with a history of substance use disorders, 4 in 10 to almost half of whom reported increased consumption during this period.

Other key findings:

  • Up to one in two respondents with current mental health symptoms who use cannabis reported increased use since March 2020, compared to two in five of the general population.
  • Over one in three respondents with current mental health symptoms who use alcohol reported consuming more since the start of the pandemic.
  • Moderate and severe anxiety symptoms were highest among respondents with a history of substance use and mental health disorders. Respondents’ top stressors were their financial situation (14%), social isolation (12%), and the health of family members (11%).
  • Only 24 per cent of respondents with problematic substance use and 22 per cent with current mental health symptoms have accessed treatment since March.

Summary Report Two: Survey Three (T3) and Survey 4 (T4)

Leger conducted further surveys in early 2021; a third survey of 1502 Canadians between January 15 and 25, 2021, and a fourth survey of 1524 Canadians between March 1 to 14, 2021.

The second summary report in this series explores the substance use and mental health impacts of the pandemic by gender and household type, drawing on data from all four surveys. Childcare and financial situation were found to be the most commonly reported stresses for people living in households with young children, especially females.

Females living in households with children under the age of 13 were more likely to report symptoms of anxiety and increased substance use than the general population. Of those surveyed, 37% of females and 24% of males living with young children reported moderate to severe anxiety symptoms. Since November 2020, 37% of females and 26% of males living with young children and who use alcohol reported increased use.

Other key findings:

  • More females reported concerns with mental health and more males reported problematic use of substances.
  • People living alone were more likely to report moderate to severe depression symptoms (20% vs 15%), thoughts of suicide (9% vs 6%) and problematic alcohol use (31% vs 22%) compared to other survey participants.
  • Childcare stress is more common among females in households with children (14%) than males (4%); financial situation and social isolation continue to be major pandemic stressors.
  • Only 18% of people with current mental health symptoms and 20% with potential problematic substance use say they accessed treatment in February 2021.
