The Montreal Canadiens open the Eastern Conference first round of the 2026 Stanley Cup playoffs at Tampa’s Amalie Arena on Thursday, April 17[1]. The Tampa Bay Lightning will host the Canadiens in what media outlets describe as a classic underdog‑vs‑favorite showdown.

Both clubs qualified for the postseason by finishing in the top eight of the Eastern Conference, but the Canadiens are viewed as underdogs seeking an upset against a higher‑seeded Lightning team[7]. Their performance could reshape the early dynamics of the Eastern bracket and set the tone for a playoff season marked by parity.

During the regular season the two teams split their meetings, leaving the series tied at two wins each[4]. The most recent encounter on April 9 saw Montreal edge Tampa Bay 2‑1[5], a result that fuels belief the Canadiens can replicate that success in the postseason.

The Stanley Cup Playoffs feature 16 teams competing in eight best‑of‑seven series[3]. Each series winner advances to the next round, with the ultimate goal of hoisting the Stanley Cup in June.

First‑round games are slated to begin on Saturday, April 19, 2026, according to the league’s official schedule[6]. AP News, however, notes that the Canadiens‑Lightning opener is set for Thursday, creating a minor discrepancy between sources[1]—both dates fall within the opening weekend of the playoffs.

Beyond the Canadiens‑Lightning matchup, the remaining seven first‑round series pit the Boston Bruins against the Detroit Red Wings, the New York Rangers against the Columbus Blue Jackets, and other conference pairings. Analysts expect several tight contests as teams that barely secured playoff spots look to capitalize on any slip‑ups by higher seeds.

**What this means**: Montreal’s underdog status adds intrigue to the opening night, and a win could signal a deeper run for a franchise that has struggled in recent playoffs. Conversely, a Lightning victory would reinforce the importance of regular‑season seeding and could set up a more predictable path for the Eastern Conference’s top teams.

The Canadiens enter as underdogs seeking an upset against a higher‑seeded Lightning team.

Montreal’s ability to upset Tampa Bay could reshape the Eastern Conference narrative, giving the underdog momentum that often fuels deeper playoff runs, while a Lightning win would reaffirm the advantage of higher seeding in a tightly contested field.
