A Toronto Maple Leafs fan who held up a "Toronto Stronger" sign outside of the Air Canada Centre during Game 3 on Monday night has caused anger in Canada and the United States.
The sign, inspired by the Boston Strong message that spread after the Boston Marathon bombing, was spotted by various sports journalists and members of the crowd in Toronto.
Not surprisingly the reaction online was fierce and hostile. See some of the reaction in our slideshow below.
"Toronto Stronger? C'mon guys figure it out that's not right #Classless," tweeted @For_The_Boys

What this unsuspecting Leafs fan also didn't realize is that the sign raised the ire of Boston's prickly and highly dedicated sports fans. Some suggested that the body of Tamerlan Tsarnaev, the dead Boston bombing suspect, be buried in Toronto. Authorities in Massachusetts are having a difficult time finding a graveyard that will take Tsarnaev's body.
Other Boston fans had fun with Photoshop and created other fake signs.
But the most moving reaction to the sign may have come from Sarah Connors at SB Nation.
"For you to try to co-opt that for a stupid sporting event? For you to take to twitter and make light of our suffering over a HOCKEY GAME?
It's heartbreaking. Nothing short of heartbreaking," she writes on the site.
The Bruins won Game 3, 5-2 and spoiled the Leafs first home playoff game in nine years. Boston leads the series 2-1.
CORRECTION: An earlier version of this story named the original sign Boston Stronger. It is Boston Strong.
