Trudeau government warned stats on seniors spending may no longer be valid

The Trudeau government is being warned to tread carefully on a promise to find a new way of ensuring that seniors' benefits keep pace with rising costs.

The idea of a so-called ``seniors' price index'' stems from a 2005 study by Statistics Canada that showed the cost of goods purchased by older Canadians is growing faster than the rate of inflation.

Currently, increases in seniors' benefits are tied to the traditional consumer price index.

The government has spent millions to improve the accuracy of the index, including using a larger sample.

But a note to Social Development Minister Jean-Yves Duclos obtained by The Canadian Press says the changes mean the conclusions of the StatsCan study may no longer be valid.
