Doucet has had a varied career working in the air industry both as a marketing and sales official with a commercial airline and later as a cargo pilot.

Doucet received favourable media attention when shortly following his appointment as Energy Critic, he toured the province to visit all of its power generation facilities at his own expense.

Despite the losses received by the Shawn Graham Liberals in the 2010 provincial election, Doucet retained his seat, beating out the Progressive Conservative candidate Sharon Tucker.

As critic for Public Safety, Doucet was very vocal in his displeasure with the Government's reaction to the flooding of December 2010 and Hurricane Arthur in July 2014.

On September 5, 2017, a cabinet portfolio rearrangement by the Gallant government had Mr. Doucet in charge of Aquaculture and Fisheries, as well as Energy and Resource Development
