"Unconscious bias explains why the higher echelons of government and business are still so pale and male. It explains why women are still so woefully shortchanged in STEM jobs (science, technology, engineering and mathematics). It explains why we need to move even more aggressively to recruit women and minorities...

When Canadian STEM schools graduate a diverse blend of 50% females and males for 35 or 40 years then in 35 or 40 years take a snap shot of the workplace and I strongly suggest there will still remain statistical inequities between men and women but it won't be because the higher echelons are significantly pale and male...there will be many other cultural/religious/ethnic factors in play that already hold both men and women back.

If as Margaret suggests we need to "more aggressively recruit women and minorities" and Canadian STEM schools aren't yet graduating a representative mix of the Canadian mosaic, will immigration policy support largely STEM female & minority hires?
