CN was sold off to private interests in 1995, ReelBrew, Canada no longer has a public rail company.

"The CN Commercialization Act was enacted into law on July 13, 1995 and by November 28, 1995, the federal government had
completed an initial public offering (IPO) and transferred all of its shares to private investors. Two key prohibitions in this legislation
include, 1) that no individual or corporate shareholder may own more than 15% of CN, and 2) that the company's headquarters must
remain in Montreal, thus maintaining CN as a Canadian corporation."
