Mental health disorders affect millions of Canadians each year, encompassing a wide range of conditions such as anxiety, depression, bipolar disorder, and schizophrenia. Understanding these disorders is essential to promoting awareness, reducing stigma, and ensuring access to effective treatments. This section provides an overview of common mental health disorders in Canada, external influences on mental health, and explores the role of pharmaceutical companies in developing and providing treatment.
Mental disorders encompass conditions characterized by significant distress, impairment in functioning, or an increased risk of harmful outcomes, such as pain, disability, or even death. Beyond their effects on health and overall well-being, these disorders also impose substantial economic burdens, including absenteeism, reduced productivity, unemployment, and healthcare costs. Research on the global burden of disease highlights that mental health conditions, such as depression, generalized anxiety, and substance use disorders, rank among the leading contributors to disability worldwide (2015; https://www150.statcan.gc.ca/n1/pub/82-624-x/2013001/article/11855-eng.htm?utm_source=chatgpt.com).

The physical environment, including housing quality, access to green spaces, and urban design, plays a significant role in mental health. Poor housing conditions, such as overcrowding, excessive noise, or lack of heating, have been linked to higher rates of stress, anxiety, and depression (2014; https://ontario.cmha.ca/documents/housing-and-mental-health/). However, access to green spaces have been shown to reduce stress, improve mood and provide a buffer against mental health challenges (2014; https://ontario.cmha.ca/news/how-city-design-impacts-mental-health/).
In urban areas, factors like noise pollution, heavy traffic, and lack of community spaces can contribute to feelings of isolation and stress. Conversely, rural and remote areas often face challenges related to geographic isolation and limited access to mental health services.

Racialized and Indigenous communities in Canada are disproportionately affected by environmental degradation, such as polluted water sources and proximity to industrial waste sites. This environmental racism compounds existing mental health challenges by creating chronic stress and eroding community well-being (2020; https://www.nationalobserver.com/2020/07/08/opinion/canada-also-has-environmental-racism-problem).
