Blaikie defeated Elmwood NDP MLA Jim Maloway, a well-known politician in the area and once the area's MP, to win the party's nomination at a meeting Monday evening at Club Regent.
"We really just had a kind of bread and butter organizing campaign," he told CBC News on Tuesday.
"We found people who had maybe voted for the NDP in the past, but hadn't been members, and asked them to come to their living room to meet a nomination candidate and to talk about federal politics. And we brought in a lot of new members that way."
Blaikie works as an electrician but also has a master's degree in philosophy and plenty of political experience — he was once an adviser to Manitoba cabinet minister Theresa Oswald.
His sister, Rebecca Blaikie, is the federal party president.
Bill Blaikie represented the Transcona and Elmwood-Transcona ridings for the NDP from 1997 until 2008. He also represented Elmwood as an NDP MLA and cabinet minister from 2009 until 2011.- From 2011: Bill Blaikie leaving political life
His son said he hopes to reclaim the riding for the NDP, which was held by Maloway from 2008 until he lost to Conservative Lawrence Toet in the 2011 election.
"We felt that it was time for a change, and that was part of the results of the last election in terms of the message sent to the NDP, and [we] felt that we could provide that," Daniel Blaikie said.
With a federal election expected to be called sometime in the fall of 2015, all political parties have started to select their candidates.
On June 16, Liberal members nominated Jim Carr as their candidate in Winnipeg South Centre.
Carr defeated Karen Taraska-Alcock, the wife of longtime Liberal MP Reg Alcock, and Maurice Alexander for the nomination.
And on May 27, city councillor Dan Vandal was acclaimed as the Liberal candidate for St. Boniface.
