Often clashing for memorable matches in MLS and the Canadian Championship, the rivalry renews once against on Wednesday in the first leg of the Canadian Championship final. Here's a look back at the rivalry.
Roots of the rivalry
Montreal vs. Toronto, in any sport, will spark animosity. It's been no different in soccer.
As the two teams are now, their first competitive match against each other came before MLS, in the inaugural Voyageurs Cup in 2008. Toronto took that first meeting 1-0 at Stade Saputo, the first seed of shared history between the clubs, though Montreal won the first iteration of that tournament and qualified for the Concacaf Champions League. Toronto got revenge the next season, scoring six unanswered goals in a 6-1 victory en route to their first of four successive trophies in the Canadian Championship.
Their first MLS match came in 2012, in front of a big crowd at the Olympic Stadium in Montreal, where the Impact drew first blood with a 2-1 win.
The first time the rivalry turned to the playoffs was in 2015. A star-studded affair, featuring Didier Drogba, Nacho Piatti and Patrice Bernier vs. Sebastian Giovinco, Jozy Altidore and Michael Bradley at Stade Saputo. It was Toronto's first playoff appearance in club history, too.
Montreal stormed Toronto, winning convincingly in front of their home fans 3-0 in a Knockout Round game.
A year later, Toronto would have their revenge.
This time in the Eastern Conference Championship over two legs, the two clubs played out an instant-classic north of the border. The Impact took a 3-2 lead after leg one into Toronto -- which could have been worse as they got out to a 3-0 lead. There were more goals to be had in the second leg, as the Impact kept their lead on aggregate in the 53rd minute at 5-4 before TFC equalized and sent the game to overtime, where two extra-time TFC goals sent the club to their first-ever MLS Cup berth.
Altidore leads the rivalry in goals with 11, trailed closely by Piatti and Giovinco with 10 each.
