The high-profile fireworks show in English Bay is expected to draw hundreds of thousands of people.
Police say a visible presence is intended to deter alcohol-fuelled fights and disturbances.
Officers say they are not expecting major disruptions, but say they want to ensure safety among attendees.
Officers on foot, horseback, bicycle, in police boats, and from the air, will monitor the crowds and boats around English Bay.
This year's event runs for three nights — July 26, July 30 and Aug. 2.
The United States is scheduled for the first night's performance, followed by France and Japan on the following two.
