In 2016 the Colombian Government signed an historic peace deal with the main guerrilla group, the Revolutionary Armed Forces of Colombia-People's Army (FARC-EP) after decades of armed conflict. In the same year Canada pledged $57.4M in development funding to help Colombia recover in the post-peace deal era. Since 2016 the Peace and Stabilisation Operations Program (PSOPs) alone has invested $35.3M in the country. With the launch of Canada's Feminist International Assistance Policy (FIAP) in 2017, many of these initiatives unfolded in a new policy context and were characterised by commitments to make gender equality a priority. This study looks at the intersection of Canadian aid, transitional justice, and gender in Colombia through a feminist-institutionalist lens. It aims to assess the impact of Canadian-funded projects from these areas along a spectrum that varies from 'gendered transitional justice' to 'transformative transitional justice'. The thesis concludes that the impact of Canadian assistance is found in the in-between area of 'gendered transitional justice' and 'transformative transitional justice', characterized by some progress away from the status quo of 'gendered transitional justice', but without hitting the transformative mark. Through a feminist institutionalist lens, we argue that it is the complex socio-political landscape of Colombia overlaying the agency of Canada's implementing partners, their Southern counterparts and the agency of the donor, and the sum of these interactions that both enable and limit the full transformative capacity of the intervention and situate its impact somewhere in the middle.
