A large online retailer has purchased a fleet of drones for package delivery, and it is using them to deliver parcels to customers around Toronto. The drones were produced by DR1 Co. The self-guided navigation system used in the drones was sold to DR1 Co. by SELFDRIVE Co. SELF DRIVE Co. purchased the base artificial intelligence system from AI Co., and to train the AI, SELFDRIVE Co. used data sets that it licensed from DATA Co. The system that is used to indicate when to drop the parcel is triggered automatically when a drone is no longer flying.

While delivering a package to 124 Elm Street, one of the drones struck a person standing on the front porch and dropped its parcel on the person. The pedestrian is badly injured.

List each legal person that the pedestrian is going to sue and explain why that person should be held accountable.
