With a qualifying spouse:
Your qualifying spouse will be entitled to a monthly lifetime pension equal to at least 60% of your monthly pension, excluding any early retirement benefits, when you pass away.
When you retire, you have the option of increasing your spouse’s survivor pension to 80% or 100% of your lifetime pension. If you choose either of these options, your pension will be subject to an actuarial reduction based on the age of your spouse.
It is important to note that the person who is your qualifying spouse when you retire is, by law, entitled to receive survivor benefits when you pass away, even if you later divorce or remarry, unless that entitlement is waived in the prescribed manner prior to your retirement or upon the breakdown of the spousal relationship.
