The 48-year-old singer took to Facebook to honour Rene who had died at the age of 73 after battling throat cancer, reported Entertainment Weekly.
Dion captioned the video as, "Today, January 14th, it's been a year since Rene left us. He will always be in our hearts."
The video is a montage of Rene's family photos and footage which takes the viewer through his life.
One can also see Rene grow through the video's span - right from his upbringing years in Montreal, Canada to his wedding to Dion and other cherished moments with near and dear ones.
