The Irving Oil refinery will be spending 60 million dollars on the annual turnaround which involves maintenance work and upgrades.
The project will use 2 thousand workers including 17 hundred tradespeople, 90 per cent of them from New Brunswick with the rest coming here from Nova Scotia.
Turnarounds are considered vital to maintaining the safety of the refinery.
It's estimated the turnaround will generate 41 million dollars in consumer spending over the six weeks and be the economic equivalent of 480 fulltime jobs.
