In the middle of a hotly contested race, there's been a big change in the London West federal election campaign.
Devin Munro, who had been managing Arielle Kayabaga's campaign, has left the effort to keep the riding in the Liberal fold.
When contacted by Blackburn News on Thursday morning, Munro said he had left the campaign for "personal reasons" and declined to comment further.
Munro has a history of electoral success in the riding. He worked on and managed successful campaigns for Sue Barnes and Kate Young, and worked in the constituency offices of both MPs.
Zachary Caldwell, whose LinkedIn page says he is the Director of Parliamentary Affairs in the Office of the Minister of National Defence, has taken over the role as campaign manager.
He also spoke to Blackburn News on Thursday and declined comment other than to say that Munro left the campaign for personal reasons.
Caldwell has worked in various capacities for the Liberal party and the federal government, but has no work experience in London according to social media profiles.
Kayabaga is a first time federal candidate. She's currently the councillor for Ward 13 in London's downtown core, a position she has taken an unpaid leave of absence from for the duration of the federal campaign.
Kate Young, a two term Liberal MP, announced she was retiring from politics in March.
Kayabaga said she would be seeking the Liberal nomination in the riding the following day.
Shawna Lewkowitz of the NDP, Conservative Rob Flack, Mike McMullen of the PPC, and Libertarian Jacques Boudreau are the other candidates vying to replace Young in the riding.
