The Quebec director's second film had its North American premiere at this month's Toronto International Film Festival.
Gabrielle is produced by Luc Déry and Kim McCraw from micro_scope production company. The film was funded through the Telefilm’s Canada Feature Film Fund.
"We are very pleased and sincerely honoured to represent Canada in the Oscar race. We hope to make it as far as possible with the film," said Archambault, Déry and McCraw in a statement.
A drama about a developmentally challenged woman’s desire for sexual freedom and independence, the film was awarded an audience prize at the Locarno International Film Festival in August.
Telefilm chairs the pan-Canadian Oscar selection committee, which includes 22 voting members from government agencies and national film industry associations.
“Gabrielle has won over audiences internationally, and there’s no question that the Academy members will succumb to its charms as well," said Carolle Brabant, Telefilm's executive director.
The film's selection also marks the third time that micro_scope has represented Canada in the Oscar race.
The company worked on Denis Villeneuve’s Incendies nominated in the foreign-language film category at the 83rd annual awards, and Philippe Falardeau’s Monsieur Lazhar for the same category the following year.
The nominations for the 86th Academy Awards will be announced on January 16, 2014.
The Oscars will be hosted by Ellen DeGeneres on March 2, 2014.
