## Mikhail Baryshnikov defection

In 1974 Sonja's family helped Mikhail Baryshnikov defect from the USSR. Baryshnikov sprinted away after a performance in downtown Toronto to a waiting getaway car that took him to a farm near Markham, Ontario. He stayed there for a couple of days until journalists caught up to him, at which point he moved to a cottage on Lake Muskoka owned by Sonja's family. He remained there until he was assured the Canadian government would not extradite him. Baryshnikov settled in New York City quickly thereafter.
