A popular gym closed its doors after giving staff less than 12 hours notice.

More than 1,000 customers are understood to be locked out of Gold’s gym at Riverport’s entertainment and leisure complex in southeast Richmond.

Gym bosses called all 10 staff members on Sunday night, informing them not to come into work on Monday as the facility would be closed.

One staff member, who asked not to be named, said they’d heard rumours that the gym was losing money and that other businesses, such as trampolining firm Extreme Air Park and Planet Lazer, were moving into the building.

It’s not known if the gym’s members are on the hook for their already paid memberships.

When the News called Gold’s, a security guard who answered said he’d no idea where to direct staff or customers.

A call to Gold’s Vancouver gym was then directed to an accountant who asked for questions to be sent via email. No one has answered the questions.
