Telefilm has an admirable track record in this regard. 
In the early 90's I was hired as a director on a big documentary series. I had a resume to wholly qualify for the position.  

Turns out I was hired only because Telefilm had noticed there were no female directors submitted by the producers for Telefilm funding. 
Before the prod. co could get their Telefilm $$, they had to find a female. And that is what they did - begrudgingly.  
The prod. co owner refused to make eye contact with me, and I was propositioned for 'side-dates' by two of my male peers. I was married.
The experience was insulting and disrespectful.

There are excellent prod.co's in Canada who do not have to be forced to hire the best, of any gender.  The rest will continue to 'put up' with an agency's 'female' quota requirements for one reason: to protect their tax credits.  
Telefilm also now needs to do transparent follow ups after the hires to assure the experience was truly professional for all involved.
