Local media reported later that the body of the fifth hiker had been found.
Search manager Martin Colwell said: 'The tracks were at the summit and there was an obvious sheer break in the snow over the north face'.
A sixth hiker with the group had fallen behind and when he arrived at the summit of Mount Harvey in British Columbia his five friends had disappeared.
Mr Colwell said the group had apparently stepped out onto a ledge of unsupported snow, without realising it, and it collapsed under them.
"She was holding (her) mom", said Kim, who was asked by the families with connections to the Korean community in the Vancouver area to speak on their behalf.
'It's very risky, it's very deceptive, ' he said.
Colwell said rescue teams, technicians, avalanche dogs, and volunteer groups began their search again on Sunday after avalanche technicians deemed the area was reasonably safe.
Lions Bay Mayor Karl Buhr said he believes the hikers were from nearby Maple Ridge and were experienced, but they were not carrying avalanche beacons, making it harder to find them.
On Saturday afternoon a hiker contacted authorities concerned because of the collapse of the cornice on the peak of Mount Harvey, the Royal Canadian Mounted Police in Squamish said in a statement. He descended and phoned 911.
"Unfortunately, near the summit, there's some very large deep cliffs to the north", he says.
"You need to have the person found and who knew if they could even go up today", he said on Monday.
The 62-year-old North Vancouver resident says that's when he knew the entire group had fallen over.
By Sunday morning, Colwell estimates the number of volunteers had grown to almost 40.
