Theresa Charbonneau, mother of fallen soldier Cpl. Andrew Grenon, said the war in Afghanistan was worth the price she and her family paid, to see the end of days for Osama bin Laden.

Al-Qaeda leader bin Laden was killed by U.S. special forces on Sunday, and spontaneous celebrations erupted across the U.S.

Charbonneau lost her son to a Taliban attack in Afghanistan in September of 2008. The death of bin Laden gives her son's sacrifice and the sacrifice of the others who have lost their lives fighting the war more meaning, she said.

"I'm thinking that this morning there are 155 souls in heaven that are partying right now," said Charbonneau. "It means that the war in Afghanistan to me is worth it. As I say it doesn't justify the deaths but it makes them a little easier to accept."

People around Windsor, Ont., were generally excited about bin Laden's demise.

Ahmad Al-Rumaithi is Muslim, and emigrated from Iraq. He was happy to hear the news.

"I was surprised that it took the Americans that long to get him, but it's a good thing," Al-Rumaithi said. "There was over 3,000 people that got killed in 9/11, so at least they got a revenge of what they had to go through."

"I was really excited this morning when I heard the news," said Cazper Phoenix. "I woke up to the news. I think it's long overdue. I am a little worried about repercussions in the U.S. and Canada."

"I'm just worried a little more on the reaction of the extremists," said Darryl Redding. "Basically, he's a martyr now. People that believe in that faith are going to probably lash out."

That concerns Charbonneau as well. She said our troops need to be more vigilant, but she believed this moment in history is the beginning of the end of the war.

"In no way do I believe that terrorism is gone," said Charbonneau. "This world still has a lot of fighting to do, but I do believe one of the prime leaders of the terrorism is gone and I think things will change, hopefully for the better."

Theresa Charbonneau said Monday was the happiest she'd been since her son's death, and she believed more than ever that he died for a worthwhile cause.
