Taxpayers' ombudsman Sherra Profit says her office has received ongoing complaints about difficulty proving or maintaining eligibility for the Canada Child Benefit despite repeatedly raising the issues with the government and the Canada Revenue Agency

The Canada Child Benefit isn't indexed to inflation for now, and the Liberals haven't agreed to do that until 2020 - after the next scheduled federal election in 2019.

In its annual report to be released Thursday, the group Campaign 2000 says the Liberal government's new income-tested child benefit could fall short of its lofty goals because it isn't automatically adjusted to combat rising food and housing prices.
