Many Montrealers showed up to sing the anti-Stephen Harper tune known as Harperman at Dorchester Square on Thursday.

They joined hundreds of people who gathered in other cities across Canada to sing the song.

The tune was originally written by Tony Turner, a migratory bird specialist who works at Environment Canada.

Turner is on administrative leave from work for making and posting a video performance of the song. At issue is whether Turner violated the code of ethics that all public servants must adhere to — one that mandates they be impartial and non-partisan.

The song criticizes Conservative Leader Stephen Harper's time in government and urges voters to support another party on election day, Oct. 19.
