RCMP say a man in his mid-20s was found wounded near a house where the violence erupted at about 6 a.m., and that it appears to have been a targeted hit.
Officers say a man and a woman, also in their mid-20s, arrived at a nearby hospital at about the same time and that the man had been shot while the woman suffered an undisclosed minor injury.
Sgt. Dale Carr says all three people were known to police and that investigators don't believe it was a random attack so the public was not at risk.
Officers are canvassing the neighbourhood, where residents awoke to sounds of gunshots, glass breaking and yelling.
Police have linked dozens of shootings in Surrey since March to the low-level drug trade, with Thursday's incident involving shots fired from a car at another vehicle just before 2:30 a.m.
