Liberal MP Nate Erskine-Smith confirmed on Tuesday that he still intends on resigning his Toronto seat this summer.

The news comes even as he lost his bid to seek the Ontario Liberal nomination in Scarborough Southwest this past weekend.

Erskine-Smith, who is looking to run for the Ontario Liberal leadership, said he would resign his federal seat once the Scarborough Southwest provincial byelection was called.

But he told CTV on Tuesday that after his defeat, he was still planning on resigning.

This will open up what’s expected to be a competitive race in Beaches-East York.

Liberal sources told iPolitics that lawyer and former senior staffer Claire Seaborn is considering running for the Liberal nomination there.

Seaborn is an environmental and climate change lawyer who advises on complex energy and mining projects at Torys. She served as chief of staff to Jonathan Wilkinson when he was natural resources minister.

Sources say she hasn’t made a decision just yet, however.
