PARIS — Before there was Penny Oleksiak and her haul of Olympic medals and before there was Summer McIntosh on her current quest, there was a lone tiny Canadian woman who set the swimming world ablaze.

Before everything fell apart for Elaine Tanner.

They called her Mighty Mouse — she still goes by that nickname — and more than half a century after the 1968 Olympic Games in Mexico City, after years of being estranged from Swim Canada, after suffering from depression, two divorces, anxiety, eating disorders and too many thoughts of ending her life, she is home in British Columbia with her husband John, as maybe the biggest swim fan in Canada.
