The Ice Bucket Challenge raises money for research into neuromuscular disease ALS. Also known as Lou Gehrig’s Disease, it’s characterized by the death of nerve cells that leave voluntary muscles paralyzed.

The challenge originated in the U.S. and spread thanks to social media. It involves pouring a bucket of ice cold water onto someone’s (or your own) head, then challenging others to do the same. Many recorded themselves doing the challenge and posted the video to Facebook or Twitter as proof they completed it.

Last year, the province’s ALS Society received nearly $2.7 million in donations from almost 79,000 people, in large part due to the spotlight the challenge put on the disease.

The ALS Society of Quebec says it plans to revive the challenge every August until a cure for the disease is found, but it wants to emphasize the giving aspect. While many people posted their videos, not everyone donated.

Former Canadiens and Bruins hockey player PJ Stock said he was one of the people who did the challenge without donating. Stock challenged his brother Dean to do it too. Months later, he found out Dean had been diagnosed with the debilitating disease.

“That’s a lesson to all of us. … We’re dealing with it on a day-to-day basis,” he said.

The ALS society says the donations are spent on ALS research and on improving services for Quebecers living with the disease.
