The founding of a formal education system in Canada was influenced by religious, racial and classist biases and bigotry that continues to perpetuate within and throughout our institutional systems today; creating barriers of access, practices of othering and underrepresentation in areas that economic, social and academic advancement of specific populations within Canadian society. This final research paper will explore the history of education in Canada, identify whom are identified as underrepresented student populations and explore early Postsecondary education (PSE) intervention access initiatives for underrepresented populations offered in publicly funded colleges such as Centennial College, George Brown College, Humber College and Seneca College, which are located in Toronto. This paper will explore the complex intersectionality amongst underrepresented groups, barriers to accessing and navigating PSI systems, explore intersectoral partnerships that encourage and support early PSE intervention planning as well identify and critique social capital gains through early PSE intervention initiatives. This paper will argue that throughout Canada’s history the explicit and implicit practice of exclusion has created a systemic system of underrepresentation of Indigenous, marginalized (including Black, 2SLGBTQ+, first-generation and females), French speaking and economically disenfranchised student populations within the PSE system. This underrepresentation has resulted in the call for early access intervention initiatives that support equitable PSE accessibility that acknowledges the intersectionality of individuals identified within these underrepresented populations as well as eliminating the legacy of institutional bigotry and exclusive practices within the fabric of the Canadian education system.
