Thank you for the question. It depends on which amendments. As you know, the federal government regulates about 10% of pension plans in Canada—the federal jurisdiction corporations like telecommunications, the airlines, the banks, and so on. Most of these changes would affect only those pension plans, except the tax changes. The government does intend to increase the pension surplus threshold under the Income Tax Act to 25% from 10%. That will apply to both federally and provincially regulated defined benefit plans.
