Trevor Kloschinsky is charged with first-degree murder in Rod Lazenby's death last year.
Lazenby died in hospital on Aug. 10 from injuries he got while responding to a dog-related call at Kloschinsky's home in Priddis, Alta., just south of Calgary.
Lazenby was an RCMP officer for 35 years, often working undercover in Vancouver.
He had retired in 2006 and was employed by the Municipal District of Foothills to enforce bylaws.
The preliminary hearing has been scheduled from Aug. 6-23.
