Medical supplies hit the edge of the edge park medical supply warehouse on Thursday.
The blaze started in the basement and quickly spread to the roof.
The roof was damaged and a large amount of medical supplies and equipment was destroyed.
The fire started at about 9:30 p.m. and has since been contained.
The company, owned by a medical supply manufacturer, said in a statement that it has a zero-tolerance policy for fire.
They say it is a matter of safety.
The National Energy Board is investigating.
