New federal regulations allow Canadians to apply retroactively for disability benefits, and a member of Parliament from P.E.I. is concerned that not everybody knows it.

Charlottetown MP Shawn Murphy is worried some Islanders may not be aware they now qualify for the federal Disability Tax Credit.

"There are people out there that would qualify for this disability tax credit that are not taking advantage of it right now," said Murphy.

Murphy said changes were made to the definition of disability in the past year.
