Investigators believe Sunday's incidents are linked to other recent shootings.
Police responded to reports of gunfire just before 6 p.m. and found evidence of shots fired but no reported injuries or property damage.
Officers say witnesses saw a silver vehicle leaving an area in the municipality south of Vancouver.
About three hours later, police responded to reports of shots being fired at a home just blocks away.
Delta Police say no one was inside at the time, but a man who is known to police and used to live in the area is believed to have been targeted.
