While the coal port facility did not release a public statement on the incident, a Port Metro Vancouver spokesperson told the Vancouver Sun that the blaze broke out about 12.50pm.
The fire was out by about 1.15pm.
Officials are reportedly still examining the extent of damage and determining cause.
Late last year, the facility’s Berth 1 was hit by a vessel, causing significant damage and shutting down that portion of the port for months.
In February, Westshore confirmed it would spend $C210 ($US201) million for a capital expenditure project to replace its three oldest stacker-reclaimers and make other improvements.
The staged project is projected to take four to five years.
Westshore is the largest coal export facility in North America.
