SHERBROOKE, Que. — A class-action lawsuit has been approved almost two years after a train derailment and explosion killed 47 people in Lac-Megantic, Quebec.

But the Quebec Superior Court justice’s ruling means it is far more limited in scope.

Justice Martin Bureau has given the plaintiffs permission to go after only two companies – World Fuel Services and Canadian Pacific Railway.

Initially, the legal action targeted 37 different parties, including Irving Oil, the now-bankrupt Montreal Maine and Atlantic Railway and its former president, Edward Burkhardt.

In January, victims of the rail disaster reached a major financial settlement with Montreal, Maine and Atlantic Canada.

The lawsuit alleges C-P-R was negligent and there was a lack of prudence in all circumstances leading up to the tragedy.

The lawsuit was filed by three Lac Megantic residents – Guy Ouellet, Serge Jacques and Louis-Serge Parent – on behalf of all the victims.

The exact amount being sought will be determined at a later date.
