HAMILTON — Substitute Bryce Duke’s 52nd-minute goal gave CF Montreal a 1-1 draw — and a valuable away goal — in the opening leg of its Canadian Championship quarterfinal with Forge FC on Tuesday.

David Choiniere, whose younger brother Mathieu started for Montreal, opened the scoring in the 31st minute for the Canadian Premier League champion, which had perhaps the best of the first half but seemed to lose its way after Duke’s equalizer.
