Important to note, and point out, that the budget simply sets out their intention to address the gender imbalance when it comes to immigration. Smart money says they will position it as targeting more women (perhaps gender specific draws at various points)That bold part. Instead of "less qualified man" it is "less qualified woman" getting selected ahead of the man. It is definitely wrong to select candidates based on their gender, and although Canada has full autonomy to select whom to invite, discriminating between candidates is unlawful in their own rules. I am not a lawyer but I think it is something that can be challenged in court with high chance of winning it.
A lot of Canada's immigration plan and targets, center around reversing the ageing population - which means having more younger people in the workforce, but also more people having babies. Biology dictates that only a certain demographic can physically do that bit, so that balance is all the more important.
Until they actually announce something concrete concerning this, it is all just speculation at this point.
