Thank you very much, that's very clear.
Basically, when workers negotiate their collective agreement, they either ask for a bigger hourly or annual wage, or they take a pay cut to get a better pension. If the company goes bankrupt and they have decided to take higher wages, they may not get their final paycheques; if they have made the trade-off of taking lower wages to get a better pension, the pension will be underfunded by the company, because the current law allows it. The company will tell their employees that it's legal and it's okay for them to lose 20% to 30% of their pension, as you were saying earlier.
What are your comments on the current situation, and on what Bill C‑228 does in fact solve, concretely, for pensioners?
