Route 117, the Trans Canada Highway Northern Route, is a provincial highway within theCanadian province ofQuebec, running betweenMontreal and the Quebec/Ontario border where it continues asHighway 66 east ofMcGarry, Ontario. It is an important road since it is the only direct route between southern Quebec and theAbitibi-Témiscamingue region.
Route 117 was formerly Route 11 and ran from Montreal north towardsMont-Laurier and then followed theGatineau River south towardsGatineau. This routing is joined withAutoroute 15 from Montreal northwards towardsMont Tremblant. Route 117 also takes in the former Quebec Routes 58 and 59.
Along withAutoroute 15 toSainte-Agathe-des-Monts, it is also listed as a branch of theTrans-Canada Highway.Ontario Highway 17 is also a branch of the Trans-Canada Highway but is an unrelated route that parallels it by about 200 km (120 mi).
This description of Route 117 follows it from southeast to northwest.
Route 117 starts in Montreal at theDécarie Interchange whereAutoroute 40 andAutoroute 15 (Décarie Expressway) meet. Montrealers sometimes unofficially extend Route 117 along the portion ofDécarie Boulevard that runs parallel to the Décarie Expressway.

From the Décarie Interchange, Route 117 goes north on Marcel-Laurin Boulevard to Keller Boulevard. It continues from Laurentian Boulevard to Keller Boulevard, southbound only, or on Lachapelle Street from Keller Boulevard, northbound only, and crosses theRivière des Prairies over theLachapelle Bridge toÎle Jésus. It continues through theLaval neighborhoods ofChomedey,Fabreville andSainte-Rose, northbound as Boulevard Curé-Labelle, Boulevard Chomedey at the formerChenoy's deli, left turn at Boulevard Cartier and back into Boulevard Curé-Labelle, southbound as Boulevard Curé-Labelle.
At theRivière des Mille Îles, it crosses over theMarius Dufresne Bridge to the "North Shore" (of theRivière des Mille Îles). Then, Route 117 runs parallel to Autoroute 15 untilSainte-Agathe-des-Monts and goes through theLaurentian Mountains. Towns along the route in this section include:
After Sainte-Agathe-des-Monts, Route 117 continues as a four-lane divided highway and winds its way throughLaurentides Regional County Municipality until it reaches the town of Labelle. From then on to the Ontario border, Route 117 is mostly a standard two-lane highway. InGrand-Remous, Route 117 crosses theGatineau River and intersects withRoute 105, which goes southwest toManiwaki andGatineau. Towns along the route in this section include:
From Grand-Remous, the route heads north for some 220 km (140 mi) through undevelopedwilderness, most of which is part ofLa Vérendrye Wildlife Reserve. While the reserve is popular for a variety of outdoor activities, services along the road are sparse. This section is often considered one of the most dangerous routes in the province because of numerous fatal accidents, some involvingtractor-trailers. During the winter, the route is often extremely slippery, even during dry and clear days. The few communities along this section are:
After the intersection withRoute 113, which continues north toLebel-sur-Quévillon, Route 117 heads west to Ontario where it becomesHighway 66. The section between Rouyn-Noranda and Arntfield runsconcurrent withRoute 101. Towns along the route in this section include:
The rivalry in theQuebec Maritimes Junior Hockey League between theVal-d'Or Foreurs and theRouyn-Noranda Huskies, the only two QMJHL teams in the Abitibi-Témiscamingue region, is known asLa Guerre de la 117 (French for "The War of the 117") due to both teams' home cities, Val-d'Or and Rouyn-Noranda, being located along Route 117.[2][3]
