Ontario surgeon Ken Walker wrote newspaper columns for half a century

Diana MacKay remembers accompanying her dad, Dr. Ken Walker, on his rounds at Niagara General Hospital when she was six, her little legs having to run to keep up with him as he dipped in and out of patient rooms.

She waited outside or with the nurses at their station while he did his work. It was in these moments that his colleagues would tell her how much they had learned from her father, how he was making the world a better place.
