Margot Kidder, who was born in Yellowknife and went on to star opposite Christopher Reeve in the Superman movies, has died at the age of 69.
Her cause of death was not immediately announced.
Kidder was born in Yellowknife in October 1948, one of five children to mom Jill Wilson and dad Kendall Kidder.
She became an actress in Canadian TV and film in the 1960s before her big break as Lois Lane opposite Reeve's Superman in 1978, plus three sequel movies.
Kidder was still appearing in shows this year, following decades of balancing acting commitments with political and environmental activism.
The website TMZ, which was the first to report her death, said she passed away at her home in Montana.
The Yellowknife street Lois Lane stands in lasting tribute to Kidder's Superman role, though Cabin Radio understands the road was – by remarkable coincidence – originally named for another resident by the name of Lois.
