The Lagimodiere facility produces cooked hams, back bacon, fresh sausages and value-added ham products
While some areas of the facility, including ham boning operations, have resumed production on their normal schedules, other areas of the plant will require temporary repairs and it is expected to take a minimum of a week to resume production.
The fire did not damage the expansion and work underway to expand bacon processing at the facility will continue, the company said.
Maple Leaf Foods, headquartered in Toronto, Canada, has operations across Canada, the US, the UK, and Asia. The company reported sales of $4.9bn ($4.93bn) in 2011.
