Bombardier has submitted an application for the CSeries flight test permit to Transport Canada, as it moves a step closer to the aircraft's first flight.
The Canadian regulator confirms today that it has received the airframer's application and says that it is "reviewing the information and documentation".
The flight test permit is the final requirement before flight testing can begin, something that Bombardier has said would begin in the "coming weeks" since July.
The crew for the first flight will include chief pilot Chuck Ellis, first officer Andy Litavniks and flight test engineer Andreas Hartono.
The CS100, known as FTV-1, rolled out of the paint shop at Mirabel airport on 22 August, after low speed taxi tests began six days earlier.
