There are several drivers to the costs of benefit packages provided to employees. There are price and volume factors. There can be increased costs for prescription medicines and certain treatments, over which the government has little, if any, control. With volume, as an aging public service or as we bring in younger workers, you can have costs at both ends in terms of medical costs and parental leave, maternity and paternity leave.
A further driver we have taken to this committee in the past consists of requirements owed to our veterans. There have been court decisions with respect to the offset of pension reductions, and there have been increased costs as a result of some of those decisions.
