The Canadian Food Inspection Agency is investigating Mowi brand smoked salmon because it may be contaminated with bacteria that causes botulism.
Mowi cold-smoked Norwegian Atlantic Salmon has been recalled in Ontario because it could allow for the growth of Clostridium botulinum.
The smoked salmon was sold in 113-gram packages between March 27 and April 10, and the agency says there have been no reported illnesses associated with eating it.
The food inspection agency says anyone with the affected products should throw them out or return them to the store.
The agency says its investigation could lead to more products being recalled.
Food contaminated with Clostridium botulinum may not look or smell spoiled but can still make people sick with botulism.
