Glee star Cory Monteith, 31, who played Finn Hudson in the Fox TV hit, was found dead at the Pacific Rim Hotel in the city centre on Saturday, said police.
The cause of death was not immediately apparent, police say, but foul play has been ruled out.
Cory Monteith, who had been in the musical comedy since its 2009 start, was treated for drug addiction in April, and had a history of substance-abuse.
His body was found by Pacific Rim staff after he missed his check-out time on Saturday, said Vancouver’s Deputy Police Chief Doug Lepard.
Cory Monteith had returned to his room at the Pacific Rim alone early on Saturday morning having been out with friends earlier in the evening, said Deputy Police Chief Lepard.
Coroner Lisa Lapointe said: “We do not have a great deal of information as to cause of death.”
Cory Monteith had been dating Lea Michele, who played his opposite number Rachel Berry in Glee, which follows a group of American secondary school misfits in their quest for singing contest glory.
Lea Michele loved and supported her long-term boyfriend and was proud he was seeking help, she told People magazine at the time.
Calgary-born Cory Monteith described himself on Twitter as “tall, awkward, Canadian, actor, drummer, person”.
Cory Monteith was treated for drug abuse aged 19 and had been open about his battle against addiction, telling one interviewer he took “anything and everything”.
