One Week is a 2008 Canadian drama film written and directed by Michael McGowan and starring Joshua Jackson, Liane Balaban, and Campbell Scott. The film debuted at the Toronto International Film Festival on September 8, 2008, and was released theatrically in Canada by Mongrel Media on March 6, 2009.

Jackson plays Ben Tyler, who has been diagnosed with cancer. Requiring immediate treatment, he instead decides to take a motorcycle trip from Toronto across Canada to Vancouver Island. Along the way, he meets several people that help him reevaluate his relationship with his fiancée Samantha (played by Balaban), his job, and his dream of becoming a writer.

The scenic backdrop of the Canadian landscape as well as an all-Canadian soundtrack serve as prevalent influences in the film.

Joshua Jackson won Best Actor at the 2010 Genie Awards for his portrayal of Ben Tyler. Liane Balaban was nominated for Best Supporting Actress.
