An increasing number of Canadians surveyed in a BMO study have invested in a registered retirement savings plan this year. The BMO Financial Group survey found 67 per cent of respondents have an RRSP, compared to 61 per cent at this time last year. And nearly three-quarters of respondents plan to contribute the same amount or more to their RRSP than they did last year. Among those who do not have an RRSP, half say they plan to open one in the next five years. Last year's average contribution amount was $4,670. The survey was conducted online among 1,000 Canadians. Online surveys cannot be assigned a margin of error.
