The jury trial for Travis Vader is set to begin in Edmonton on April 28, 2014.
The trial is scheduled to last seven weeks.
Lyle and Marie McCann of St. Albert, a bedroom community north of Edmonton, were reported missing in July 2010.
The seniors were last seen alive gassing up their motorhome for a trip to British Columbia.
The burnt-out vehicle was found west of Edmonton two days later, but the couple's bodies have never been found.
