According to IANS, TIFF co-director Cameron Bailey lauded the actor's performance in the picture.
"Dhobi Ghat has Aamir Khan in a role of an artist that you often don't see him in - he has done a terrific job," he said.
Director Kiran Rao also won praise from the festival organiser.
"I think she is part of a generation of filmmakers that we are seeing come up now in India - a new school in international cinema.
"This generation is not making films out of the Indian commercial cinema context, but making films that are referencing American independent cinema or European cinema or Asian cinema," said Bailey.
Dhobi Ghat is expected to release commercially at the end of 2010.
