Arrow stars Stephen Amell and Emily Bett Rickards were spotted filming a scene in downtown Vancouver on Thursday.
The hit CW television series took over the former Canada Post building to film scenes involving a food drive at the Star City Police Department.
Although Canada Post has left the premises for several years, the building is still highly actively used as production space for the local film industry.
The show is currently in its sixth season, and the success of the series based on DC Comics has spurred the creation of Flash and Legends of Tomorrow, which are also filmed in the city.
These three shows, plus Supergirl, will begin filming their annual four-show crossover beginning next week.
