Public memorial to be held Friday in Calgary for former premier Peter Lougheed

CALGARY - A public memorial honouring former premier Peter Lougheed is to be held on Friday in Calgary.

The service is to begin at 1 p.m. at the Southern Alberta Jubilee Auditorium.

Limited seating is available for the public on a first-come basis beginning at 10 a.m., but overflow seating will be available at SAIT's campus gymnasium.

Mourners have been filing past Lougheed's flag-draped coffin at the Alberta legislature where he is lying in state until late Tuesday.

Lougheed, premier of Alberta from 1971 to 1985, died last week of natural causes at age 84.
