The symbolic gesture has swept across North America following an emotional Sunday vigil at the Broncos鈥� home arena in Humboldt, where thousands turned out to mourn the 15 individuals who lived and breathed Canada鈥檚 most beloved sport.

TSN radio broadcaster Brian Munz appears to have popularized the stick trend by sharing a photo and message from one of his friends.

鈥淟eaving it out on the porch tonight,鈥� the text said, beneath a photo of a hockey stick. 鈥淭he boys might need it鈥� wherever they are.鈥�

Munz invited others to do the same, in a tweet that has been liked and retweeted thousands of times.

Tributes have also been pouring in from the United States and elsewhere.

A GoFundMe page set up for the families of the victims has raised more than $4.7 million since Friday, and messages of sympathy have continued to trend online under the hashtags #HumboldtStrong and #PrayforHumboldt.
