MONTREAL- CN (TSX: CNR) (NYSE: CNI) announced today that the company has registered with the Office quebecois de la langue francaise (OQLF) pursuant to An Act respecting French, the official and common language of Quebec (the 'Act ').

Further to the Act coming into force in 2022, CN management began discussions with the OQLF to voluntarily register the company. As it is subject to the Official Languages Act under its incorporating act, CN is in a unique situation. The discussions held with the OQLF over the past few months sought to find a way to reconcile the obligations under this federal law with CN's intention to voluntarily register with the OQLF.

'I welcome CN's decision to register with the Office quebecois de la langue francaise, as have the vast majority of federally regulated companies with more than 50 employees. This registration by a large federally chartered company is very important for Quebec and its French reality. I strongly hope that this step by CN will encourage the few remaining companies to do the same and comply. We must all take strong actions for the French language.'

Jean-Francois Roberge, Minister of the French Language, Government of Quebec

'This voluntary act we are making today is in line with our company's rich history in Montreal, Quebec, where our headquarters has been located for more than a century. French is the official and common language of Quebec and we are proud to do our part in promoting and protecting French.'

Tracy Robinson, President and Chief Executive Officer, CN
