Richardson fell on a beginners' trail Monday during a ski lesson at Station Mont Tremblant, said the statement from the resort, located about 130 kilometers (80 miles) northwest of Montreal. She was not wearing a helmet, the resort said.
At the time, Richardson was accompanied by a veteran ski instructor, who called the ski patrol, the statement said. The ski patrol members examined her and found no sign of injury.
"As standard protocol, the ski patrol insisted that Ms. Richardson be transported to the base of the hill in a rescue toboggan," the resort statement said. Once at the base of the hill, staffers advised Richardson to seek additional medical attention, but she declined.
Accompanied by the instructor, Richardson went to her hotel, where she was again advised to see a doctor, the resort said. The instructor stayed with her as a precaution.
"Approximately an hour after the incident, Ms. Richardson reported she was not feeling well," according to the statement.
An ambulance was called, and Richardson was taken to the hospital.
The statement offered no details about her condition or injuries.
Richardson, 45, has appeared in many television, film and stage roles, including the movies "Nell" and "The Parent Trap." She won a Tony award in 1998 for her performance as Sally Bowles in "Cabaret." She married actor Neeson in 1994.
The Montreal Gazette reported that Richardson's two sons with Neeson were skiing with her at the time of her fall, and that Neeson flew from a Toronto film set to be with her at the hospital in Montreal.
