Just for clarification, I've only joined NAPO in the past month, so I'm on a steep learning curve on this issue and on other things.
One thing I have found out is that there is a current case that has not yet gone to trial, which challenges the clawback of the national child benefit supplement, which is a federal benefit given to families with children. My understanding is that all jurisdictions, save one or two, are clawing back the same amount that is given to the recipients of that benefit. So if I'm a parent and I'm receiving $100 now from the federal government in terms of the national child benefit supplement, that amount can be taken off other payments I may receive from, for example, the Province of British Columbia.
So where you have a situation of one or two jurisdictions not clawing back the supplement when others are clawing it back, right away you have a pretty serious situation of inequality.
