OAS is earned at the rate of 1/40th of the full basic amount (currently $564.87 monthly) for every year of residence in Canada. If you will have 18 complete years of residence in Canada when you turn age 65, you will receive 18/40ths of $564.87 = $254.19 monthly.
For 2011, the maximum OAS benefit is $540.12/month or $6,481.44/year. To receive this, you would need to have lived in Canada for 40 years after the age of 18. Anything less than 40 years results in a reduced old age security benefits.
