Several groups that are opposed to the railway bypass say they are displeased with the federal government's decision and are studying legal options.

The Quebec and federal governments say they will jointly fund a rail bypass in Lac-Megantic, nearly five years after 47 people were killed when a train derailed and exploded in the town.

Some Lac-Mégantic residents say Prime Minister Justin Trudeau has failed in what they call his moral obligation to have a rail bypass built around the Quebec town.
