Three military transports carrying 272 Canadian evacuees from Haiti have arrived in Montreal.

Two planes arrived early Friday morning, with another plane landing hours later.

Four more planes are expected to arrive by Saturday morning carrying an additional 400 evacuees, Quebec civil security officials said.

Friends and family, who had waited hours at Trudeau airport, greeted the weary travellers, many of whom were draped in Red Cross blankets. Some were injured and bandaged, including one woman who still had blood on her face. Several were pushed through the airport terminal in wheelchairs.

"I haven't slept in three days," one of the quake survivors said. "It was hell."

The evacuees had been selected by staff at the Canadian Embassy, which remains functional despite sustaining damage.

Foreign Affairs Minister Lawrence Cannon said more than 100 Canadians in Haiti have taken refuge in the embassy, while 48 others are being assisted. About 6,000 Canadian citizens live in Haiti, but only 700 were registered with the embassy in Port-au-Prince, Cannon said.

Meanwhile, the number of Canadians known to have been killed in the devastating quake has climbed to four, after one of two missing Mounties was found dead.

The body of Sgt. Mark Gallagher was found in the rubble of the residence where he was staying in the capital city, RCMP Commissioner William Elliott told a news conference in Ottawa on Thursday. "We are now doing everything possible to recover Mark's body and arrange for his repatriation," he said.

Gallagher, 50, had spoken to his wife in New Brunswick on Tuesday, just half an hour before the earthquake hit, to say he was going to bed. He had worked as a public relations officer for the RCMP in the Maritimes but went to Haiti because he wanted more of a challenge, his wife told CBC.

Another Mountie, Supt. Doug Coates from Ottawa headquarters, was still missing, said spokeswoman Patricia Flood.

The other three victims include Georges Anglade, a Montreal university professor for 30 years, and his wife, Mireille. They were visiting friends in Port-au-Prince and were killed when the house they were in collapsed. Yvonne Martin, a nurse from Elmira, Ont., who arrived in Haiti's capital on Tuesday afternoon, about 90 minutes before the earthquake hit, was also among the dead.

There is confusion around the fate of Serge Marcil, a former Liberal MP believed to have been located after being reported missing in Haiti. There were reports Marcil had been rescued and flown to Miami for medical treatment. It now appears those reports were premature, and it's not clear Marcil has been rescued at all.

United Nations spokeswoman Alexandra Duguay and UN worker Jean-Philippe Laberge were also among Canadians unaccounted for.
