CPR's Montreal & Western Railway was built as the Montreal Northern Colonization Railway Company through to St-Jerome by 1876 (to Ste Agathe des Monts (mp 44.4 from Ste-Thérèse) in 1892, to Labelle (mp 80.2) in 1894, to Nominingue (mp 103.7) in 1903 and to Mont Laurier (mp 138.2) in 1909).
The line beyond Ste-Agathe was abandoned by 1989 and the southern reaches were abandoned the next year, allowing construction of the
le P'tit Train du Nord trail which also hosts the Trans Canada Trail.
