The Environment Canada scientist whose anti-Stephen Harper folk song "Harperman" got him suspended from his job is retiring rather than waiting out an investigation into his behaviour.

The Professional Institute of the Public Service of Canada, the union that represents Tony Turner, said Turner's retirement took effect this week.

He was suspended with pay this summer for allegedly breaching the government of Canada's values and ethics code for public servants by recording and posting a song on YouTube that takes the prime minister's policies to task and concludes that "Harperman, it's time for you to go."

In a release, Turner said he was assured of a quick investigation, but as the weeks have dragged on he decided it was better to retire from the civil service.

Turner said he continues to believe he acted within his rights under the Charter of Rights and Freedoms and says he did not act contrary to Environment Canada's values and ethics code.

A spokeswoman for the public service union said Turner's retirement does not affect the rights of other civil servants to
free political speech, a right that was upheld by the Supreme Court of Canada in 1991.
