Isn't the reserve chute the Old Age Security pension along with the Guaranteed Income Supplement?
Assuming a single person with no other income, they would add $11,378 to the maximum CPP payout of $18,092 for a total of $29,470 or $14,918 to the average CPP payout of $11,000 for at total of $25,918. (Unlike the CPP, OAS is clawed back if you have other income over a certain amount.)
Retiring at 70 would raise the maximum CPP to $25,690 and OAS to $12,272 for a total of $37,962.

Not a huge amount but substantially more. Renters also seem eligible for other help at these income levels which might amount to $5,000 per year in BC.
