Contract ratified at Heligear-Northstar Aerospace.
The workers voted 63.8% in favour of the new three year deal.
It was the second tentative deal the workers voted on.
On Sunday, the workers rejected the first tentative deal by a 51% margin, resulting in a two day strike.
Unifor Local 444 represents the workers and president Dino Chiodo says there are significant wages increases.
"There's no signing bonus in this collective agreement but individual employees are receiving from a minimum of four percent and some employees as much as 20 percent raises over the course of this agreement. We have employees that are going from $22 right to $26 a hour as soon as ratification occurs so there are some good pieces. People will also be able to enjoy their birthdays off starting in 2019.)
The deal also includes pension and benefit improvements.
There are 62 unionized employees at the Lakeshore plant.
The workers return to work Wednesday morning.
