Parliamentary experience Parliamentary Secretary to the Minister of Finance From 2003 to 2006, McKay served as Parliamentary Secretary to then Finance Minister Ralph Goodale. Paul Martin, during his tenure as Prime Minister, implemented a number of reforms aimed at making parliament more democratic. One of these reforms gave greater authority to MPs serving as Parliamentary Secretary to a Minister, in contrast to their previous role that had been largely clerical with little purview over government policy. To this end, McKay was given ministerial responsibility for the improvement of partnerships between the public and private sectors.
