Thousands of Indigenous families living on-reserve will miss out on a boost to the federal Liberals’ signature child benefit that government MPs plan to tout at dozens of events Thursday.

Almost every family in the country receives the monthly benefit, but take-up rates for families on-reserve have consistently lagged behind the wider population – largely chalked up to lower tax filing rates among Indigenous families.

Tax returns are the basis for calculating how much a family receives under the Canada Child Benefit.

The government now estimates one in every five Indigenous families on-reserve who should qualify are not receiving the benefit, an improvement from two years ago when about half of families on-reserve missed out on the means-tested benefit.
