Despite looming uncertainty about the testing system for British Columbia-based productions, the Warner Bros. Television (WBTV) shows Batwoman, Riverdale and Maid resumed shooting on Wednesday, having received the clearance.

According to reports, the shows — along with CBS TV's Nancy Drew and Charmed, and several Disney shows — were forced to stop filming last week due to delays in processing COVID-19 tests in British Columbia, where a single lab company, LifeLabs, is approved to oversee the testing for the US-based productions.
