Norde, who was awarded the 'Best Player of the Season' for Mohun Bagan in the 2015-16 I-League, will be seen adding extra firepower at the front for Mumbai City FC yet again this season.
The 26-year-old finished with three goals and three assists during his debut season of the ISL with Mumbai City FC last year.
Norde recently made an appearance for the Haiti national team in the Copa America in the USA.
On being retained by Mumbai City FC, Norde said, "I can't wait to get back to training with the team and meeting the fans."
Team owner and Bollywood actor Ranbir Kapoor said, "We're delighted to have Sony back. He's been one of our best players and is coming off a great season in the I-league as well. He was one of the first names that we wanted back and are glad to have him wearing our colours."
