I would say there is a minister responsible for status of women in Canada. At the highest political level, there is clear leadership there.
Within each organization--and there may be some variability in terms of the practice--but certainly within TBS the champion is an assistant secretary--so an assistant deputy minister--as are all of the champions for the various types of areas where we have a champion, like official languages, employment equity, and sustainable development. They are all at the assistant secretary level.
They are the senior executive team within the secretariat. Each of those champions is responsible for promoting that particular issue or matter within the secretariat, ensuring that the practices of the secretariat align with and meet expectations that exist for whatever that particular area may be, including GBA.
