Your province may vary.

In BC there is a long tradition of the Provincial Government using Employee Pension deductions to provide below market loans for projects such as the WAC Bennett Dam, the Vancouver Trade and Convention Centre expansion, and the Livent performance venue.

By below market I mean BC Hydro getting the money at 2% below what Vancouver was paying for Sewer and Drain bonds at the same time, and well below what low Risk Stocks returned in dividend and Capital Gain income.

OTOH the BC Pension plan was historically cheap to run because the typical worker used to be a secondary school dropout who resigned to raise a family before she had the 10 years of service needed to draw a Pension.
