He was 90 years old, according to the CBC.
As a foreign correspondent for the CBC, Schlesinger covered some of the most significant news events of the latter part of the 20th century and early 2000s.
He bore witness to historical events from Vietnam to the fall of the Berlin Wall and the first Gulf War, and he did so in his inimitable way, with his accented English, his gimlet eye for detail and the elan of a born storyteller.
"You could see the way he talked to the camera, embraced the camera," former CBC News chief correspondent Peter Mansbridge said today from his home in Stratford, Ont.
"In translating the story to all of us, whatever that story was, wherever he happened to be. Whether he was in Zimbabwe, being gassed by Zimbabwean soldiers, whether he was in Vietnam, whether he was in the streets of Paris during riots. He knew how to tell a story in a way that could really embrace the viewer. That's an art form."
