Mainline Passenger rail service in Newfoundland ended in 1969.) and Prince Edward Island (the former PEIR), as well as numerous branch lines in Nova Scotia, New Brunswick, Southern Ontario, throughout the Prairie provinces, in the British Columbia interior, and on Vancouver Island. Virtually every rural area served by CN in some form was affected, creating resentment for the company and the Government of Canada. Many of these now-abandoned rights-of-way were divested by CN and the Government of Canada and have since been converted into recreational trails by local municipalities and provincial governments. CN's railway network in the late 1980s consisted of the company's Canadian trackage, along with the following U.S. subsidiary lines: Grand Trunk Western Railroad (GTW) operating in Michigan, Indiana, and Illinois; Duluth, Winnipeg and Pacific Railway (DWP) operating in Minnesota; Central Vermont Railway (CV) operating down the Connecticut River valley from Quebec to Long Island Sound; and the Berlin subdivision to Portland, Maine, known informally as the "Grand Trunk Eastern", sold to a short-line operator in 1989. In 1992, a new management team led by ex-federal government bureaucrats, Paul Tellier and Michael Sabia, started preparing CN for privatization by emphasizing increased productivity. This was achieved largely through aggressive cuts to the company's management structure, widescale layoffs in its workforce and continued abandonment or sale of its branch lines. In 1993 and 1994, the company experimented with a rebranding that saw the names "CN", "Grand Trunk Western", and "Duluth, Winnipeg, and Pacific" replaced under a collective CN North America moniker. In this time, CPR and CN entered into negotiations regarding a possible merger of the two companies. This was later rejected by the Government of Canada, whereupon CPR offered to purchase outright all of CN's lines from Ontario to Nova Scotia, while an unidentified U.S. railroad (rumoured to have been Burlington Northern Railroad) would purchase CN's lines in western Canada. This too was rejected. In 1995, the entire company including its U.S. subsidiaries reverted to using CN exclusively. The "CN Commercialization Act" was enacted into law on July 13, 1995, and by November 28, 1995, the Government of Canada 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.
