The Liberals have dropped an Alberta candidate after some previous comments came to light.
Chris Austin had been selected as the candidate for Sturgeon River-Parkland, but the Liberals said Wednesday that new information brought to their attention led them to drop him.
"Some of Chris Austin's views, as articulated in past comments, are irreconcilable with the values of the Liberal Party of Canada," the party said in a statement.
The Liberals did not elaborate on those past comments. But a Twitter account bearing the same name posted a link to a video of last year's Parliament Hill shooting, writing, "Harper has turned our Nation's Capital into a War Zone as his thirst for War."
The account also posted a link to a news article about the Communications Security Establishment Canada, one of Canada's principal security services, and wrote, "The Gestapo Of Canada lol :)"
The same day a post linked to a story about the CBC firing Jian Ghomeshi with the comment, "Will Canada Become A Fascists Dictatorship?"
The Liberals' new candidate for Sturgeon River-Parkland, Travis Dueck, is expected to be acclaimed at a nomination meeting Thursday.
Past comments have also felled two other Liberal candidates during this campaign.
Liberal Joy Davies quit as a candidate in the B.C. riding of South Surrey-White Rock, over pro-marijuana comments on Facebook. Ala Buzreba, a Liberal running in Alberta, resigned over offensive Twitter messages.
On Tuesday the Conservatives dismissed their sixth candidate since the start of the election campaign. Blair Dale, a candidate in Newfoundland, was removed because of comments posted on Facebook that were "incompatible" with the party, a spokesman said.
Morgan Wheeldon resigned as NDP candidate in the Nova Scotia riding of Kings-Hants after controversial comments he allegedly made on Facebook about the Middle East.
