The Burnaby RCMP is investigating the death of a couple found just after 8:00 p.m.
RCMP Inspector Tim Shields says they were found on the floor of their trailer located around 14th Avenue and Willard Street.
He says a neighbour had gone to check on the pair, when the man did not show up for work.
Shields says the neighbor looked into the trailer and saw the man and woman lying on the floor, unresponsive.
"It appears that possibly some sort of a gas leak contributed to these deaths. It is still too early to tell definitively what exactly took place here. We don't know if foul play was involved, but we should know more in a couple of hours."
Shields believes the bodies could have been there for a few days.
He says they are working with the fire department and the coroner to determine what happened.
