First of all, we talked about the gap on, I believe, page 5 of the English brief. It's on page 5 in the French version as well.
The gap is that 62.7% of the average annual amount is paid to women as compared to their male counterparts. On the bottom you'll see the graph that shows that wage gap pictorially. If you look at the bottom of that graph--and I apologize for the very small print, which is very taxing at my age--the first bullet says:
Include immediate annuities, disability retirement benefits, and annual allowances payable to former contributors only
You can see here that the benefits being paid out are not simply full pensions; they also include people who go off on disability pensions and people who are injured on the job and go out through assorted pensions. It's not a reflection of those who go off on an unreduced pension. A lot of things here actually show the difference from a purely gender perspective, but given that we can't factor out the unreduced pensions piece, we can't show you with hard numbers a really solid comparison between men and women.
You also asked a question about leave without pay for workers. The answer depends on the type of leave without pay that workers go off on. For some types of leave without pay, such as maternity and parental leave, the employer continues to pay the employer's share. However, when the worker comes back from maternity or parental leave, they would then pay their share for their absence.
For other types of leave, such as relocation for spouse, I believe the employee is the person who ends up paying their share, meaning the employer's share and then their share for the current period when they come back to work. If, for example, you had taken three years of leave without pay to follow your spouse to the House of Commons, and you couldn't get a job as a public sector worker in Ottawa, you would be paying triple superannuation when you got back to your job. You would triple your contributions. The same is the case for things like education leave. That can be dependent on the employer's discretion.
You can see that for situations such as spousal relocation leave, we don't have the hard statistics. Treasury Board would be able to provide you with those, but I'm quite certain that the majority of those cases would be women following their male spouses.
You asked a question about the $30 billion and the lawsuit. That was a few years ago, and we're actually going through the court case. It was back in 1999; it was Bill C-78. It was $30 billion, and it came from the three federal public service pension plans.
