Danielle Smith, David Emerson, Belinda Stronach among high-profile defectors

Toronto-area MP Eve Adams announced today that she is leaving the Conservative Party to sit as a Liberal, citing her dissatisfaction with the policies of the Stephen Harper government.

- Eve Adams, former Conservative MP, to join Liberal Party
Adams was first elected for the Conservatives in 2011 in the Toronto-area riding of Mississauga-Brampton South, but had hoped to run again for the Tories in the newly created riding of Oakville North-Burlington.
A bitter nomination contest ensued and she was forced to drop out, partially because of allegations that her fiancée Dimitri Soudas, at the time the executive director of the Conservative Party, was meddling in the campaign.
Adams said she'll run for a Liberal nomination in the Greater Toronto Area but declined to identify the riding.
Here is a list of five other prominent floor crossings in Canadian politics.
Nine Wildrose MLAs, including then-leader Danielle Smith, crossed to Alberta’s governing Progressive Conservative party in December, in a move some political observers called unprecedented.
The floor crossing reduced the provincial opposition party to five MLAs and increased the PCs seat count to 72.
Smith defended her decision to switch parties in an interview with CBC Radio's The House, calling it a victory for the Wildrose Party.
"We took down two administrations — the [Ed] Stelmach administration and the [Alison] Redford administration — that were leading the province in the exact wrong direction," she said.
"To me, it's declaring victory and uniting conservatives under the leadership of one person so that we can deal with some very significant challenges ahead."
David Emerson defected to the federal Conservatives in 2006, just two weeks after being elected as a Liberal MP in the Vancouver-Kingsway riding.
Harper surprised political observers by appointing Emerson as trade minister on Feb. 6, 2006, the day the government was sworn in.
During the election campaign, Emerson had promised to be a thorn in Harper's side if the Conservatives formed a government.
Bernard Shapiro, then the country's ethics commissioner, cleared Emerson and Harper of wrongdoing after opposition MPs complained that the prime minister broke the conflict of interest code for members of the House of Commons by offering an "inducement" to Emerson in the form of a cabinet position.
Belinda Stronach left the federal Conservatives on May 17, 2005, joining the Liberals under Paul Martin as minister of human resources and skills development. She had run for the leadership of the Tories just one year earlier.
Two days after her defection, Stronach's vote was instrumental in keeping Martin's minority Liberal government alive. The vote on a budget amendment ended in a tie, broken by the House Speaker in favour of the government.
Several Quebec members of the Liberals and Progressive Conservatives, including then Tory environment minister Lucien Bouchard, left the party to sit as Independents in 1990.
The disaffected MPs formed the Bloc Québécois.
Jack Horner was first elected to the House of Commons as a Progressive Conservative from Alberta in 1958. He was re-elected six more times.
He lost the Tory leadership race to Joe Clark in 1976, and in 1977 he crossed the Commons floor to sit with the Liberal government. He was given a cabinet position, but lost his seat in the 1979 election.
