The British actress and mom of two is in critical condition.
She fell in a beginners trail while taking a ski lesson at Station Mont Tremblant.
She was accompanied by an experienced ski instructor who immediately called the ski patrol. She did not show any visible sign of injury but the ski patrol followed strict procedures and brought her back to the bottom of the slope and insisted she should see a doctor.
As an additional precautionary measure, the ski instructor as well as the ski patrol accompanied Mrs Richardson to her hotel. They again recommended she should be seen by a doctor. The ski instructor stayed with her at her hotel. Approximately an hour after the incident Mrs. Richardson was not feeling good. An ambulance was called and Mrs. Richardson was brought to the Centre Hospitalier Laurentien in Ste-Agathe and was later transferred to HĂ´pital du Sacre-Coeur.
Richardson, 45, is the elder daughter of Oscar-winning actress Vanessa Redgrave and the late director Tony Richardson, and belongs to a British acting dynasty.
Her maternal grandparents were the actors Michael Redgrave and Rachel Kempson, and her uncle Corin and aunt Lynne Redgrave are also both actors. Sister Joely Richardson is also an actress, best known for starring in TV series "Nip/Tuck."
In January, Richardson and her mother played the roles of mother and daughter in a one-night benefit concert version of "A Little Night Music," the Stephen Sondheim-Hugh Wheeler musical, at the Nokia Theatre Times Square in New York.
She married Neeson in 1994, and the couple has two sons.
Our thoughts are with Natasha Richardson and her family in this time.
