That's a good question.
With regard to the barriers, it's clear there will always be people who do not believe there is a place for us within the organization. The organization per se does not hold that view, but rather society. We often hear that the CAF is a group that represents Canadian society as a whole. Some CAF members hold similar views.
You started your question by mentioning representation. I think it's very important. Indeed, our first Black general officers in the military, namely Rear Admiral Olivier and recently Commodore Williams, were recently appointed.
I think that the current representation among senior officers will encourage people and demonstrate to everyone in the Canadian Armed Forces that there is room for all Canadians.
