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)
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.
