CBS

A five-year stint with CBS News is highlighted by his award-winning coverage of the Persian Gulf War. McKeown was the first reporter to broadcast from the front lines during Operation Desert Storm and reached Kuwait City as Iraqi troops were fleeing, almost a day before allied forces arrived. People Magazine wrote: "McKeown and his crew survived artillery, minefields and Iraqi snipers to get the best story of the Gulf War."

While at CBS, he was also a correspondent for two prime-time newsmagazines, Street Stories and America Tonight, and contributed to 48 Hours and the CBS Evening News.

The Fifth Estate

In January 2005, McKeown challenged a statement made by American conservative polemicist Ann Coulter during her Fifth Estate interview. Coulter had asserted that Canada's non-participation in the 2003 invasion of Iraq demonstrated that Canada's "loyal friendship" with the United States was weaker than in the past. As part of her broader attempt to compare the Canadian response to the Iraq war with that of Vietnam, Coulter erroneously asserted that "Canada sent troops to Vietnam." McKeown corrected her, "No, actually, Canada didn't send troops to Vietnam."^[2] Although no uniformed Canadian troops were involved in war, Canadians did participate through counterinsurgency efforts in South Vietnam and reconnaissance for US bombing runs in North Vietnam.^[3] Later during an interview on the American C-SPAN channel, Coulter stated that McKeown did not mention that 10,000 Canadian troops ran across the border to enlist in the United States army. She also went on to call McKeown "a bubble-head, a Ted Baxter." She had said she would get back in touch with the CBC, but has yet to do so.

McKeown has also taken on other conservative pundits, such as Fox News Channel host Bill O'Reilly, whom he accused of lying and distorting facts, while trying to convey the news to the American people. McKeown used O'Reilly's reference to what he called the "Paris Business Review" and the billions of dollars France had lost due to the boycott that he had initialized following France's decision not to participate in the 2003 invasion of Iraq. McKeown pointed out that trade between France and the United States actually went up since O'Reilly initialized the boycott and that the Paris Business Review does not even exist.^[2]

In 1982, McKeown anchored a special Fifth Estate report about animal cruelty in Hollywood, focusing on the 1958 Walt Disney film White Wilderness as well as the television program Mutual of Omaha's Wild Kingdom. In the report, McKeown found that the lemming scene was filmed not at the Arctic Ocean, but at the Bow River near downtown Calgary, where the lemmings were forced into the river; in addition, he also discovered that the footage of a polar bear cub falling down an Arctic ice slope was in actuality filmed in a Calgary film studio.^[4][5][6] In light of the findings for the report, McKeown asked Wild Kingdom host Marlin Perkins if he had deliberately injured or killed animals while making wildlife films. Perkins, then in his seventies, "firmly asked for the camera to be turned off, then punched a shocked McKeown in the face."^[7]

In a November 2016 CBC News article, McKeown, a former CFL player who dealt with concussions during his football career, announced that he would donate his brain to the Canadian Sports Concussion Project.^[8]

Documentary films

In addition to hosting The Fifth Estate in the 1980s, McKeown produced, wrote and directed several critically acclaimed documentaries. These include The Boys on the Bus, an intimate portrait of the Edmonton Oilers as they won the 1987 Stanley Cup, Les Canadiens, a history of the Montreal Canadiens, and Strangers in a Strange Land, which depicted the trials and tribulations of a Canadian movie crew in China as it shot a feature film about the legendary doctor, Norman Bethune.
