If you are considering a significant increase in public pensions, you have to set things in their proper context and look at the issue from different angles. First, regarding employers who integrate their own pension plan with a public one, it is clear that if you increase public pensions, you will decrease the cost of the private plan, so you won't get any push back from the employers. The difficulty with increasing public pensions, either by increasing the public pension rate or by increasing the share of the salary which will be covered, is that, today in Canada, these plans are voluntary. Private pension plans are voluntary. So, it is clear that when you increase premiums—and there's been talk of a 40% increase in premiums—small- and medium-sized enterprises will perceive this as yet another payroll tax. Whether you agree with this or not, that is how it will be perceived. So there will be a problem of competitiveness, a problem of costs, which will be harder to bear than one might think.
On the employer's side, at least, there will be a major problem, especially for companies which, for now, for all kinds of reasons, have chosen not to provide a pension plan. This becomes a serious issue.
