Yup.

We've had at least thirty years of programs encouraging women to enter tech fields. Is there a girl of high school age anywhere in Canada  who is good at math and who has not been explicitly encouraged to consider engineering? And when many of these women later on "leak" out of the pipeline, why does no-one think that perhaps they were given bad advice? 

Maybe it's time to start thinking about why the programs are not working, rather than doubling and tripling down on more programs.

You know - act like an engineer. If something you built isn't doing what you want, you don't turn it on again and again expecting a different result.
