 Tim Hortons Field, which opened in 2014, was built both as a venue for the 2015 Pan American Games and as the new home of the Hamilton Tiger-Cats football team; its predecessor, Ivor Wynne Stadium, was originally built for the first Commonwealth Games.Other Canadian cities never expressed interest in building a venue for Major League Baseball or the Summer Olympics, and felt no need to replace their smaller, open-air stadiums used mostly for Canadian football.For example, Calgary's open-air McMahon Stadium dates from 1960 and has been used only for Canadian football, the 1988 Winter Olympics, and an outdoor ice hockey event (the 2011 Heritage Classic).
