Joan Stirling’s application was rejected by Citizenship and Immigration Canada because she  couldn’t produce a specific piece of identification — her birth certificate from almost a century ago.

Her friend, Diana Watson, has been fighting since 2012 to get Stirling recognized as a Canadian citizen, in part, so the senior could access public health care.

Watson provided Citizenship and Immigration Canada (CIC) with a mountain of proof, more than 20 documents that tracked Stirling’s birth in the U.K., her arrival in Canada, and her long history here.
