Pittsburgh Penguins captain Sidney Crosby and Steven Stamkos of the Tampa Bay Lightning will share the Rocket Richard Trophy after each finished the regular season with 51 goals.
The three-way goal-scoring race went down to the final whistle.
Washington's Alexander Ovechkin headed into Sunday with 50 goals but failed to score against Boston.
Crosby scored twice against the New York Islanders later in the day to pull ahead with 51, but Stamkos scored into an empty net with 13 seconds left to pull even against Florida.
Crosby missed a strong chance near the end of the third to finish ahead for good, and didn't get the overtime winner for the Penguins.
It is the second time since 1999 when the Richard Trophy was first handed out that there has been a tie.
Stamkos led all NHL snipers with 24 power-play goals, six more than the nearest competitor.
Art Ross Trophy
Henrik Sedin of the Vancouver Canucks ended the season with a huge flourish, notching four assists in the team's final game on Saturday to earn the NHL scoring title.
Sedin led the league with 83 assists and 112 points, marking the first time a Vancouver player has won the Art Ross.
Crosby was eight points behind Sedin heading into Sunday, but by the halfway point of Pittsburgh's game against the Islanders had already picked up five points.
Crosby didn't pick up another point but technically finishes ahead of Ovechkin for second in points on the basis of more goals.
Ovechkin still has a shot at winning a third consecutive Hart Memorial Trophy as most valuable player when the finalists are named in the coming weeks.
Ovechkin teammates Mike Green and Jeff Schultz also earned distinctions. Green led all defencemen with 19 goals and 76 points, while Schultz had a plus-minus rating of plus 50 to lead the NHL.
Martin Brodeur added another accolade to his illustrious career as the New Jersey Devils finished with a 2.27 goals-against average, the lowest in the league.
It will be the fifth time Brodeur and the Devils take the William M. Jennings Trophy for fewest goals against. Backup Yann Danis shares in the award.
Brodeur also led the league with nine shutouts, 45 wins, and 76 starts.
As a result, Brodeur could be in the mix when the finalists for the Vezina Trophy for top goaltender are named. Buffalo netminder Ryan Miller and Ilya Bryzgalov of the Phoenix Coyotes are also strong candidates for the Vezina.
Boston rookie Tuukka Rask led all goalies with a minimum standard of games with a 1.97 goals-against average of 1.99 and save percentage of .931.
Colorado's Craig Anderson had the heaviest workload, facing a league-high 2,233 shots on net.
Colorado centre Matt Duchene led all first-year skaters with 24 goals and 55 points, while Buffalo defenceman Tyler Myers had 37 assists to lead all rookies.
No. 1 overall pick John Tavares of the New York Islanders endured a mid-season drought but finished strongly to end up one point behind Duchene. Tavares notched 24 goals and 30 assists.
Rask led all rookie goaltenders with five shutouts, but started 22 fewer games than Jimmy Howard of the Detroit Red Wings. Howard led with 63 appearances, compiling an impressive 37-15-10 record for Detroit with a 2.26 average.
Vancouver forward Alex Burrows and Marian Hossa of Chicago each finished with five short-handed goals, tops in the league.
Dany Heatley of San Jose scored nine game-winning goals to lead all players, while Ottawa centre Mike Fisher and Buffalo forward Derek Roy were the overtime go-to guys, with three goals each.
Heatley's teammate Scott Nichol was tops on the draw with a 60.6 faceoff percentage, just ahead of David Steckel of Washington.
Ovechkin was again the busiest sniper, leading with 368 shots despite missing 10 games.
Among players with a minimum standard of shots, no one had a higher shooting percentage than Minnesota veteran Andrew Brunette (19.4).
Carolina defenceman Joni Pitkanen led all skaters in ice time with an average of just over 27 minutes per game, while Tampa Bay's Zenon Konopka topped all NHL tough guys with 265 penalty minutes.
