Wil Wheaton at POLARIS Richmond Hill this weekend

Sci-fi, fantasy and mixed genre fans are invited to attend Polaris — the largest fan convention of its kind in the Greater Toronto Area this weekend. Currently in its 26th year and formerly called Toronto Trek, Polaris is Friday evening through Sunday at the Sheraton Parkway Toronto North Hotel at Leslie Street and Hwy. 7.

Wil Wheaton - star of Stephen King's 'Stand By Me', 'Star Trek: Next Generation', 'Big Bang Theory', and 'Eureka' - is among the celebrity guests who will be speaking, signing autographs and posing for photos with fans. Others include Miracle Laurie ("Dollhouse"), Neil Grayston ("Eureka", "Warehouse 13"), Tony Amendola ("Stargate SG-1", "Dexter", "Continuum") and "Star Trek" character actors J.G. Hertzler and Robert O'Reilly.
