The lawyer for a Canadian woman stranded in Kenya said he will file a motion in Federal Court on Tuesday, asking the federal government to issue an emergency passport so she can return home after a DNA test confirmed her identity.

Raoul Boulakia, the lawyer for Suaad Hagi Mohamud, said he received the genetic test report on Monday afternoon, and it proves that she is the mother of a 12-year-old boy living in Toronto, confirming who she says she is.

"The DNA test says that it's 99.99 per cent established that she is the mother of her child, Mohamed," he told CBC News.

"It means that she is definitely who she says she is," Boulakia said from Toronto. "There's no way to debate this anymore, so the government really has nothing more [it] can say about this."

Mohamud, 31, hasn't been allowed to return to Toronto since mid-May when she tried to leave Nairobi following a two-week visit with her mother there.

Kenyan immigration officials said her facial features looked the same, but her lips looked different than those of the person in the passport photo, according to a document from Kenyan authorities.

Canadian officials in Kenya confiscated her passport and concluded she was an impostor.

The Canadian government later wrote to the Kenyan government informing officials there that it had done a thorough investigation and determined her to be an imposter and recommended that she be prosecuted.

Kenyan officials charged her with identity fraud, and Mohamud's court case began in May but was put on hold pending the DNA test, Boulakia said.

With results in hand, Boulakia said he will file a motion Tuesday asking the court for an emergency passport so she can be repatriated to Canada and reunited with her son.

Canadian officials in Kenya confiscated the passport of Suaad Hagi Mohamud and concluded she was an impostor. On learning the DNA results, Mohamud told CBC News she jumped for joy, but still wonders why it happened to her.

"She's been through hell," Boulakia said. "She's been in prison in Nairobi … This'll be a light at the end of the tunnel."

Son Mohamed Hussein, who hasn't seen his mother for three months, told CBC News he was elated and relieved that she'll be able to return to Canada.

"I'm feeling very happy … that she's going to come back," he said.

Mohamud has said that she lost a lot of weight in the four years since her passport photo was taken. She showed the Kenyans other pieces of Canadian identification and offered to be fingerprinted. But she was charged with identity fraud and spent eight days in jail before she was released on bail.

Boulakia said the federal government should review how Canadian consulates behave when citizens go to them for help.

"Our consulates don't necessarily do anything logical to figure out a person's identity," he said.

"I'd hate to be stuck in some country and call my embassy for help and get a reaction like this."

A spokesperson for the Canada Border Services Agency, which is handling calls on the matter, said the agency recognizes the DNA results but that it cannot comment further while Mohamud's case is still before the courts.
