Western Canada expansion
In 1905, CNoR reached Edmonton, just as part of the old NWT had changed into the province of Alberta. The rail-line crossed the North Saskatchewan River at Fort Saskatchewan, coming into Edmonton from the northeast, following the present-day LRT track.[6][7]
After a pause, the CNoR began construction west from Edmonton, and by summer 1907 had gone as far as Stony Plain. A stock market crash that year ceased construction. When construction was resumed in 1910, it was found that extending the Stony Plain line meant frequent crossings over the Grand Trunk Pacific line which had been laid in the meantime. Instead CNoR decided to leave Edmonton through St. Albert. (A bump on 124th Street near Stony Plain Road is remnant of the constructed but abandoned road-bed.)[8]
CNoR's terminus on the coast changed over time. Rather than competing with the GTPR in having a terminal at the mouth of the Skeena, the CNoR accepted BC government subsidies to switch to the Vancouver area. When the GTPR selected the Yellowhead route, CNoR protests created some delay but could not overturn the decision.
In 1911, CNoR workers started on a townsite named Port Mann on the Fraser River. This townsite would accommodate new car shops, and from there, rail-lines would extend to Vancouver and the Fraser River delta. CNoR's initial expansion in the 1890s and 1900s had been relatively frugal, largely by acquiring bankrupt companies or finishing failed construction projects. By the 1910s, significant expenses were accumulating. The CNoR started construction west of Edmonton in 1910, fully two years later than GTPR. The construction through the Rockies, which was expensive, largely paralleled the GTPR line of 1911, creating about 100 mi of duplication.[9] However, the largest costs were from building on "the wrong side" of the Thompson and Fraser rivers in the Coast Mountains of British Columbia. CPR already had trackage on the desirable banks, forcing the CNoR to blast tunnels and ledges out of these canyons.
The most infamous construction folly on the CNoR in British Columbia happened in 1913, when blasting for a passage for the railway at Hells Gate triggered an enormous landslide which partially blocked the narrow swift-flowing Fraser River. The resulting damage to Pacific salmon runs took decades to reverse by the governmental construction of fishways.
