Hong Kong-based attorney Robert Tibbo said Canada needs to take this "exceptional'' step and allow the seven people to enter the country after the Hong Kong government rejected their asylum applications last Friday.
The seven people — four adults and their three children — allegedly helped hide Snowden when the fugitive was in the region in 2013 after he leaked documents revealing extensive U.S. government surveillance.
They were put in contact with Snowden because they share Tibbo as a lawyer.
Speaking from Hong Kong through a video conference, surrounded by the seven refugee applicants, Tibbo told reporters they have two weeks to appeal the decision or risk deportation to their countries of origin, Sri Lanka and the Philippines, where they fear for their safety.
He asked for donations to help cover the $15,000 he said it will cost to file the appeals.
"The solution is Canada.''
There is little chance their appeals will be successful, however, Tibbo said.
"The solution is Canada,'' he said, adding the country is one of a handful of jurisdictions that permit a review of refugee applications from people who haven't been screened by the United Nations.
Tibbo said the Hong Kong government doesn't allow the UN to screen refugee applicants into the country.
Michael Simkin, part of the families' legal team, said in Montreal his clients' file could be handled "within days'' in Canada if the government wanted to.
"More importantly, if they were willing they could bring the families to Canada as an exceptional measure'' while their claims are processed, he said. "It has been done before and can be done again.''
Lawyer Robert Tibbo and his clients Sri Lankan refugee Ajith Puspa, Nadeeka, holding her son Danath, and Filipino refugee Vanessa Rodel, with her daughter Keana, and Nadeeka's daughter Sethumdi, arrive to speak to the press outside the Immigration Tower in Hong Kong on May 15, 2017.
The families' lawyers say the Hong Kong government rejected their applications because it believes the Philippines and Sri Lanka are able to protect them.
One of the refugee applicants, Ajith, said he is convinced he will be killed if he returns to Sri Lanka.
"With Mr. Snowden moving on from Hong Kong it is my view my clients shouldn't be left behind.''
Tibbo said he has "no regrets'' about his decision to introduce the families to Snowden.
"They made fully informed decisions but at the same time I feel a moral responsibility,'' he said. "With Mr. Snowden moving on from Hong Kong it is my view my clients shouldn't be left behind.''
All four adults told reporters via video conference that they had no regrets sheltering Snowden.
Snowden remains in exile in Russia. He has been charged with espionage in the United States and could face up to 30 years in prison.
