When appearing at the Eurovision Song Contest 1988 (named in the movie "Singing Award") Aline Dieu is performing after the Danish singer Kirsten & Søren. In real life Celine Dion (for Switzerland) was the 9th performance while Denmark was the 13th performance.
When Celine Dion wins the Eurovision Song Contest ESC in Dublin, Ireland, in 1988 her parents are seen watching the show live at home in Canada. However, ESC was not broadcast live in Canada.
The Titanic song heard in the movie has strings while the version heard by Céline Dion was a simple demo with synths.
At 1H34 of the film, there is PS4 games in the bookshelf.
The Playstation 4 was released in the end of 2013.
In the early 1980s, right before Aline arrives in Guy-Claude's office for the first time, the establishing shot shows Le 1000 De La Gauchetière, a Montréal skyscraper that was only completed in 1992.
The song "Pour que tu m'aimes encore" is heard in a scene that takes place before 1995, when the song was released.
In a scene set in 1980 young Aline is listening to "Memory" from Andrew Lloyd Webber's musical "Cats". The musical didn't premiere until 1981.
In the obstetrician office in New York, images of Montreal buildings (including the cathedral) can be seen thru the windows.
Also, when Aline leaves, a building with the logo of Banque du Canada can be seen in a distance.
