The Paris terror attacks have had a tremendous impact on London's French community.

The horrific video of people scrambling out of a concert hall and running for their lives weighs heavily on all French citizens, including those working in London.

Pierre Hauss, a French citizen living in Canada, learned his friend was safe, hours after bullets flew at the concert his friend was supposed to attend.

"He said to me, 'I'm lucky. I was supposed to go to the concert and I decided not to go. I changed my mind, I decided to stay with my wife in Paris,'" says Hauss.

The events of last Friday also are shocking for Western University professor Alexandre Legros, who lived in Paris for 15 years and was in France just last week.

"So last week, it was happy. This week, how is it going to be? Probably having eyes open and looking around. But [you] can't be afraid, otherwise life can't go on," says Legros.

But life is going to go on for Legros. He leaves with his two daughters this week for an extended stay in France. His wife has already departed.

The trip has elevated his concern, but he knows that the pain of terror can touch anywhere.

"It's no different than if it was here. I'm a French citizen. It touches me a lot. I'm also a Canadian citizen and it touches me here as well. It can happen here. It's a global thing," says Legros.

"I hope we find a solution against terrorism. It's not just a French problem, it's a world problem now. It's just beyond me though. I don't know," he adds.

Meanwhile, London city council held a moment of silence Monday for the victims of the attacks and for the people of France.

Londoners wanting to show solidarity with the people of France can do so during a candlelight vigil in Victoria Park this Friday evening.

Final details surrounding the rally are currently being finalized.
