Eureka I found it!
Last summer a quirky little TV series shot in the Nanaimo region. Eureka shot its pilot in Ladysmith and a bit in the Comox Valley. The 11 episode opening season of Eureka will premiere this summer and follows a US marshal who gets stranded in the small town of Eureka, a community he discovers is actually a top-secret “brain trust” where the government has various scientists working on potentially world-altering experiments. While exterior were shot on the island interior were filmed at Vancouver Film Studios, as will be the case with the series.
I found a promotional trailer that you can watch.
