He took office on April 12, 2007.[4] On April 19, 2007, he was selected to be the Official Opposition's Shadow Minister of Environment and Sustaining Development.[5] He lost his seat in the 2008 election along with 33 other ADQ MNAs, coming in third place in his ridding with 18.46% of the vote.[6]

On May 31, 2010, it was announced Diamond had switched to the Liberal Party and would be running for them in the July 5 Vachon by-election.[7] He was defeated in that election by Parti Québécois candidate Martine Ouellet.[8]
