Ontarians with disabilities, especially people with mental health and addiction disabilities, continue to face disparities on several social and economic indicators compared to people without disabilities. They have a higher unemployment rate, are more likely to be in low income status, have lower educational levels and are less likely to live in adequate, affordable housing.
When controlling by disability type, the results show that people with mental health and addiction disabilities fare worse on most indicators than people with other types of disabilities. However, it is important to consider the complex relationship between these two groups. As the data show, the vast majority of people who report mental health and addiction disabilities (over 90%) also report another disability type. Having a chronic physical condition can be a risk factor for developing a mental health disability and vice versa.
It may be that having a mental health disability or addiction is related to low income, high unemployment, and low education, etc., compared to people with other disabilities or no disability. Alternatively, it could be that the combined effect of multiple disabilities is associated with these factors. Having multiple disabilities may contribute to greater severity of disability overall and barriers in society may be compounded, leading to increased exclusion and discrimination.
However, the relationship between disability and social and economic indicators can be complex. Is it that having a disability contributes to higher unemployment, lower education levels, and low income? Or does having low income, low education levels, poor housing and poor employment opportunities contribute to greater prevalence of disability, including mental health and addiction disabilities? Research indicates that both considerations are important.
With respect to sample size, because of the relatively small data set in Ontario, the results could not be broken down by sex, age and severity of disability. Age, in particular, is a potential confounding factor. The OHRC could not examine, for example, the prevalence of mental health and addiction disabilities among Indigenous peoples, racialized people and women, distributed across age groups, in comparison with people with other disabilities and people with no disabilities. In a further example, it is not clear whether women in Ontario are more likely than men to report other disabilities because they tend to live longer. Similarly, does the reporting of mental health and addiction disabilities for racialized people differ by age?

 Research on the social determinants of health shows that many factors, including unemployment, discrimination, poor housing, and poverty can contribute to poor physical and mental health.
