Survivor Benefits

Social Development Canada provides a summary on Canada Pension Plan Survivor and Death Benefits. I have posted an extract below:

Survivor Benefits: "Canada Pension Plan Survivor Benefits
1. What are Canada Pension Plan survivor benefits?
Canada Pension Plan survivor benefits are paid to a deceased contributor's estate, surviving spouse or common-law partner and dependent children. There are three types of benefits.
The death benefit is a one-time payment to, or on behalf of, the estate of a deceased Canada Pension Plan contributor;
The survivor's pension is a monthly pension paid to the surviving spouse or common-law partner of a deceased contributor;
The children's benefit is a monthly benefit for dependent children of a deceased contributor.
It is important to apply for Canada Pension Plan benefits. If you do not apply, you may lose benefits you are entitled to receive.
2. How long must I contribute for my survivors to receive benefits?
If your Canada Pension Plan 'contributory period' is longer than nine years, you must have contributed in:
one third of the calendar years in your contributory period, or
10 calendar years, whichever is less.
There is a minimum contributory requirement of at least 3 years."
