A teacher by career, she rose to become director of the town's school board before being elected mayor in 2002.Earlier in 2013, Roy-Laroche had announced that she would not run for another term in the 2013 municipal elections.
Following the rail disaster, however, the incumbent council's term in office was extended two years so that the town would not have to cope with an election in the middle of the tragedy and its aftermath.She earned the "Granite Lady" designation in part for her adamant refusal to permit the railway line on which the accident occurred to be rebuilt on its existing path through the downtown core.
By August 14, just over one month after the accident, the town had preliminary plans in place to rebuild the destroyed downtown.For her own part, Roy-Laroche downplayed the praise, telling the media that "I am just doing what any mayor would do when faced with disaster.
I'm the mayor of a little city of 6,000 people that has to deal with what they're calling the biggest train accident in Canadian history.
I was head of the school board, I had to deal with angry parents.
That was nothing.
I am in great health, I have a lot of energy.
My advice is, keep your health, stay in harmony with your family."In December, when the provincial government of Quebec organized a special ceremony to present the first responders in the disaster with a medal of honour for their service and bravery, Roy-Laroche herself was also named as an honoree.Through 2014 and 2015, Roy-Laroche took on a public role as an advocate for improved rail safety.
In March 2014, she travelled to Washington, DC as part of a delegation lobbying the United States Congress to improve American rail safety regulations.
