Actor Corey Haim laid to rest in Canada

The actor's funeral was held at Steeles Memorial Chapel in Toronto

A private funeral service has been held in Toronto, Canada for actor Corey Haim following his death at the age of 38 in a Los Angeles hospital last week.

Around 200 friends and family members were reportedly present, though actor Corey Feldman - Haim's Lost Boys co-star and friend - did not attend.

Writing on his website, Feldman said he stayed away "to minimize the media attention as much as possible".

"My heart is right at your side," he continued in an open letter to Haim.

"Just know I am at home today projecting positive energy for you and your passing," he wrote on Tuesday.

Police have attributed Haim's death to an apparent overdose of prescription drugs, though the official cause of death has yet to be announced.

Haim died last week at Providence St Joseph Medical Centre in Los Angeles

Authorities in California have released a 911 tape that has the late actor's mother Judy telling paramedics her son was not breathing.

"He all of a sudden got out of bed," a distraught Judy Haim is heard saying on the tape.

"He wanted to go to the bathroom and he fell on the floor and I put him on the bed and then that was it."

California Attorney General Jerry Brown has said his office is investigating a prescription drug ring linked to Haim's sudden death.

The actor, best known for his Lost Boys role as the vampire hero's younger brother, had fought drug addiction for some years.
