Ciman, who was a member of Belgium's 2014 World Cup squad, has spent his entire career in his homeland with Charleroi, Club Brugge, Kortrijk and Liege but is no looking forward to the next chapter of his playing days.
"I'm very excited to join the Montreal Impact and MLS. This will be a new adventure for me and my family," Ciman, who has sought the move to Montreal to find specialist treatment for his daughter who suffers from autism, said in a club release.
"It is also an opportunity for my daughter, so that she could have the proper support and instruction.
"I would like to thank the president, my agent and all the staff of the club for this new challenge. I can't wait to meet my new teammates, the city and the fans."
