Yvon Godin, New Brunswick's only NDP MP, will not run in the next federal election, according to sources.
Godin confirms he will make an announcement either on Friday afternoon or early next week. But he wouldn't confirm the reports of his retirement.
"I'm the only one who knows what will happen [at the announcement]," Godin said.
The reason Godin is announcing his retirement from federal politics at this point is so the party can find the next candidate to replace him, according to a source close to Godin.
Godin, who represents the riding of Acadie-Bathurst, said earlier this week he would decide in the coming days whether to retire as an MP.
"I'll have been there for 18 years. When is the right time? I don't think there's ever a right time. That's why the decision is so hard," he said.
"Any which way I will be going, it'll be one of the hardest decisions to take."
Godin was first elected to the House of Commons in 1997, after widespread anger over Employment Insurance reforms by the former Liberal government.
In 2011, he earned nearly 70 per cent of the vote share in his riding, with more than 32,000 votes.
His 53-point victory over second place Progressive Conservative candidate Louis Robichaud was the largest margin of victory for any NDP MP in that election.
