Mayor Naheed Nenshi says he was shocked and saddened to hear of the sudden passing of Jon Lord.
The 57-year-old, former Calgary alderman and provincial MLA suffered a severe heart attack at his home Tuesday night.
"Jon was a community-builder in the truest sense of the word. His legacy—in Alberta, Calgary, and especially Marda Loop—cannot be overstated," the Mayor stated in a release. "Our city has lost a champion, and far too soon. He will be greatly missed."
Lord served as alderman for Ward 8 for two terms beginning in the mid-nineties.
He then moved to provincial politics where he served as MLA for Calgary-Currie from 2001-2004.
