Partnering with the Nova Scotia Native Women's Association, Delilah Saunders-Terriak spoke to reporters in Halifax on Friday morning.
Loretta Saunders, an Inuit woman from Newfoundland and Labrador, was last seen Feb. 13.
"My family is having a difficult time processing what's going on and having a hard time finding answers," said her sister.
Saunders-Terriak described the 26-year-old woman as strong.
"She wouldn't want us wasting time crying," Saunders-Terriak told the crowd.
A crowd-sourcing site has been started to help bring Saunders's five brothers and parents from Newfoundland and British Columbia to Nova Scotia to aid in her search.
“We need to be together when we find out what’s going on. When we hear some good news," said Saunders-Terriak.
The car the Saint Mary's University student owns was found earlier this week in Harrow, Ont., south of Windsor.
