In terms of benefits, essentially the benefit structure has not changed since the implementation of the new charter in 2006, where the charter introduced a disability award effective April 2006 and essentially cancelled the monthly Pension Act benefits.
The amount of a disability award, which is a lump sum amount that is clearly for pain and suffering, is not an offset against any SISIP benefit that someone receives.
To put this in context, the benefit under the SISIP platform is 75% of a member's salary at the time of release. There is also a list of reductions that apply. Some of these reductions include the Canada Pension Plan and the Canadian Forces Superannuation Act, and maybe some earned income. Pre-2006, the monthly Pension Act was also an offset against SISIP.
That's essentially the big difference pre-charter. After the charter the DA is no longer an offset, whereas the monthly Pension Act is still an offset today if someone was to come on claims with such a benefit.
