Heale agreed terms with the club late last week after deciding to quit Rangers for a fresh challenge, moving to the club where his father Billy enjoyed great success during his famous non-league career.
Gulls' Manager John Batch said "I'm extremely pleased that Danny has agreed to come and play for Canvey. Danny is a player who has great qualities and a superb scoring record, and I'm sure he will prove to be a huge asset to the team and club over the coming season. Danny is very excited about the move and he can’t wait to get involved with the squad and start playing his football at the Brockwell Stadium”
The Gulls hope to announce further signings over the coming days.
