"I felt very strongly that if there was a chance to save Philadelphia a thousand good union jobs, blue-collar jobs, I was going to work to bring people together the best I could to help make it happen," MacDonald said in an interview before Sunoco announced Monday its joint venture with the Carlyle Group to keep the refinery operating.
Officials singled out MacDonald's commitment to find a partner to run the refinery, which Sunoco had pledged to shut down if it was unable to to find a buyer.
He has built up a reservoir of good will with figures as diverse as Gov. Corbett and Leo W. Gerard, international president of the United Steelworkers, who became the first labor leader ever quoted in a Sunoco news release April 23, when the company announced it was entering joint-venture negotiations with Carlyle.
"We've been impressed with Brian MacDonald's open-mindedness," said Gerard, a native of Ontario, who joked that "the Canadian connection always works."
MacDonald came to Sunoco in 2009 after working in executive positions with Dell Inc. and General Motors Corp. He took over from Lynn Elsenhans, a career oil-industry executive.
Corbett said that he did not want to disparage Elsenhans, but that MacDonald communicated a greater willingness to find a solution and that they struck up an immediate rapport.
"I'm not saying she didn't have a willingness," the governor said in an interview. "With some things, you almost get a vibe, if you understand. . . .
"I think Brian understood - I guess the word I want to use is - the corporate citizenship role. Maybe he understood that better."
