VANCOUVER -- The search for a missing man in an expansive B.C. park has gotten the attention of the country's prime minister.

Jordan Naterer has been missing since the Thanksgiving long weekend when he set out for what was supposed to be a solo overnight hike in Manning Park.

The search for the 25-year-old was temporarily suspended over the weekend and colleagues of Naterer's father, who is a dean at Memorial University in St. John's, N.L., brought the matter to Prime Minister Justin Trudeau who participated in a town hall with the university on Wednesday.

"There's limited leverage I have, even as prime minister, over a local issue and a local search like that, but I can certainly ask about it and see if there isn't something I can nudge a little bit," Trudeau, whose brother died in a 1998 avalanche while skiing in B.C., said.

"I know the heartbreak that the Naterer family and the entire family is going through right now."

It's believed Naterer, who lives in downtown Vancouver but is from Newfoundland and Labrador, had been planning to hike the popular Frosty Mountain Trail. His car was found by friends in the Lightning Lakes day-use area and for days, search and rescue teams from several areas of the province scoured the area by air and on foot.

Princeton Search and Rescue confirmed the search was reactivated by the Vancouver Police Department early Thursday morning. 

Naterer's parents, Josie and Greg, said on CTV Morning Live Thursday that pieces of synthetic down material were recently found in the park, similar to material they'd found in boxes in their son's apartment. 

"Another reason that we felt confident about that is because it was in an area that wasn't checked by the search and rescue team," Greg said. 

"So I think this is where our thinking is now, that he could be slightly outside the lines that were drawn by the search and rescue team."

Josie said her son was well-equipped for winter camping and had a proper sleeping bag, down-filled coat, food and appropriate footwear.

"We're leaving no stone unturned," she said. 

A special weather statement is currently in place for parts of Manning Park, as Arctic air is expected to bring below seasonal temperatures through the southern part of the province. Early snowfall is also expected.
