The first paramedics to arrive were turned away after Ms. Richardson declined treatment, ambulance records show, though they reported seeing the 45-year-old actress briefly from a distance. For a few minutes, they said they saw her sitting on a stretcher — not laughing and walking off her fall, as a resort spokeswoman said on Tuesday.
In Ms. Richardson’s case, ambulance records showed that she did not receive her first attention from a doctor until 4:20 p.m., at the local hospital, in Ste. Agathe, Quebec, about 25 miles from Mont Tremblant.
Yves Coderre, the director of operations at Ambulances Radisson, which serves the resort under an arrangement with Quebec’s public health care system, said in an interview on Friday morning that his service received its first call at 12:43 p.m. local time on Monday.
That is consistent with the resort’s report that the accident occurred midday. An ambulance arrived at the resort 17 minutes later; but the crew, told that Ms. Richardson did not want medical attention, left soon afterwards.
Mr. Coderre said that Mont Tremblant frequently calls for ambulances after skiers experience minor falls. And just as frequently, he said, the ambulances are turned away.
Officials at Mont Tremblant said Ms. Richardson initially declined to see a doctor on Monday, but was taken by ambulance to the local hospital about an hour later after complaining of a headache to an instructor and ski patrol member who accompanied her to her hotel.
However, the ambulance record shows that it was not dispatched to Ms. Richardson’s hotel room until 3 p.m., Mr. Coderre said. It arrived nine minutes later, and the crew began attending to her. At 3:42 p.m. it left the resort and arrived at the hospital in Ste. Agathe at 4:20 p.m.
Ambulances Radisson did not conduct the transfer to the hospital in Montreal, and it is not clear when Ms. Richardson arrived there on Monday. The Globe and Mail, a Toronto newspaper, reported on Friday that she may have arrived as late as 7 p.m.
There is no helicopter or airplane-based ambulance service in the Laurentian hills where Mont Tremblant is situated. According to Mr. Coderre those services are only available in certain regions of Quebec, like the Arctic north, which lack road access.
Early Tuesday afternoon, about 24 hours after she fell, an ambulance took Ms. Richardson from the Montreal hospital to the airport, and she was flown to New York. She was then taken to Lenox Hill Hospital, where she died the next day.
Questioned about the sequence of events, a spokeswoman for Mont Tremblant said on Thursday that the resort would no longer comment on the accident but would cooperate with any investigation.
In Quebec, there are several possible channels of investigation into the circumstances surrounding Ms. Richardson’s accident and the medical treatment she received.
Marie-Eve BÃ©dard, a spokeswoman for the minister of health and social services, said that Ms. Richardson’s family could ask the commissioners at either hospital that treated her to review the case. If the family is not satisfied, or if they believe that there were significant medical errors, it can then file a misconduct complaint with the medical licensing body for Quebec.
As for the responsibility of the Mont Tremblant resort, the provincial coroner’s office can investigate the accident or hold a public inquiry. The report of the inquiry cannot lay blame, but only make recommendations to prevent similar deaths in the future.
