Grand River Transit (GRT) is the public transport operator for the Regional Municipality of Waterloo, Ontario, Canada. It operates daily bus services in the region, primarily in the cities of Kitchener, Waterloo, and Cambridge, alongside the ION rapid transit light rail system which began service on June 21, 2019.^[3]

It was named for the Grand River, which flows through the Region; the naming also echoes the Grand River Railway, a former electric railway which served the area in the early twentieth century. GRT is a member of the Canadian Urban Transit Association.

On January 1, 2000, the Region of Waterloo created GRT by assuming the operations of the former Kitchener Transit (which also served Waterloo) and Cambridge Transit. By the end of that year, operations had been fully synchronized and buses began running between Cambridge and Kitchener; as a result, ridership in Cambridge improved dramatically, and there have been increases in service, including Sundays and late evenings Monday-Saturday.

Grand River Transit has consistently purchased low floor, wheelchair-accessible buses, principally from Nova Bus, Orion, and New Flyer, and these now form the entirety of the standard fleet. Most operating buses are less than twenty years old, though a few older buses are used primarily for high-school special runs. GRT has installed bicycle racks on the front of its buses in order to encourage the use of sustainable transport; all buses now have these racks. Bicycles are also allowed on-board Ion trains.

Service to less dense areas is provided by the busPLUS system, large vans which take regular fares on scheduled routes to new neighbourhoods and more remote facilities; if ridership is sufficiently high, these services can later be replaced with regular buses, as happened with the 71 Melran route in Cambridge.

GRT also operates MobilityPLUS, which provides specialized transit for disabled patrons using minibuses equipped with wheelchair lifts.

The GRT fleet consists entirely of motor buses. Kitchener Transit operated trolleybuses earlier in its history, but they were withdrawn from service during the 1970s, well before the systems were merged. GRT continued operating 23 compressed natural gas-driven buses inherited from Kitchener Transit but did not expand this fleet; these buses were retired before the end of 2009. Until the 1950s, the area was served by electric passenger and freight trains run by the Grand River Railway, which even earlier in the 20th century had run streetcars on city streets before the separated railway lines were built.

Since September 1, 2007, all undergraduate students at the University of Waterloo have purchased a non-refundable four-month U-Pass as part of their tuition fees for less than a quarter of the equivalent adult monthly pass.^[4]

Grand River Transit has six diesel-hybrid buses which began service in late August 2008.^[5] To get the best use of their powertrain, these buses run on routes like Route 7 King, which have frequent stops and heavy usage.^{[citation needed]}

With the launch of Ion rapid transit in June 2019, GRT's bus services were substantially reorganized. The greatest effect was in decentralizing the network in Kitchener–Waterloo by no longer using the Charles Street terminal as a service hub; the affected routes now connect with Ion trains at their stations, forming a centralized spine.

Public transit in the Grand River area began with private operators and slowly gave way to municipal run service. Interurban and streetcar service were the earlier modes and by the mid-20th century, bus transit became the norm.

The iXpress express bus service is operated by GRT consisting of six routes^[19] along main corridors in Kitchener–Waterloo and Cambridge, serving major roads in all 3 cities.

In order to increase ridership across the region and facilitate the expected growing population, the Region of Waterloo unveiled the Regional Transportation Master Plan in 2010, which consisted of seven iXpress-style routes that criss-cross the important secondary corridors along the region (with the proposed light rail serving the Central Transit Corridor), and where they are expecting the most growth to occur. These corridors include Fischer-Hallman, University, Highland/Victoria North, Ottawa, Homer Watson/Maple Grove, Coronation, and the Cambridge stubs centered around Cambridge Centre and Ainslie Street Terminal. The routes were to be phased in, with the last route being introduced in 2015. The plan was eventually scaled down in order to put more emphasis on the LRT proposal with the Cambridge stubs largely eliminated, and the timeline was also spread out, with all routes expected to be implemented by 2018.^[20]

There were different naming proposals for the new iXpress routes. During the public consultations in March 2011, the proposal was to name each iXpress route after a colour, with the letter X at the back. For example, Fischer-Hallman iXpress would be named Blue X, and the shelter would have blue stickers in order to identify each route. However, the plan was eventually dropped, and GRT decided to stick with the iXpress trademark, with route numbers being added to signify between the different iXpress routes.^[20]

Fischer-Hallman was chosen as the first corridor to have the new iXpress service, as the current route 12 serving this corridor is full during most times of the day, and residents wanted a faster service to Forest Glen, Highland Hills Mall, and the university area. During the public consultations, there were different routing proposals at the north end. Proposals ranged from having the route go all the way east on Columbia to King, south on King, west on University, and north on Phillip, to having the route go only as east as Phillip, then head south on Phillip, west on University, north on Seagram, and east on Ring Road to serve the current UW Davis Centre bus stop. Eventually, the suggested proposal was to have the route go east on Columbia, south on Phillip, east on University, and north on Hazel. This allows equal access to the north end of the University of Waterloo campus, the RIM offices along Columbia, and Wilfrid Laurier University.

The first (and now defunct) route, designated route 200 after the expansion of iXpress service, was launched in September 2005 and ran from Conestoga Mall in Waterloo and Ainslie St. Transit Terminal in Cambridge primarily along King Street in Kitchener and Waterloo and Hespeler Road in Cambridge, utilizing a short section of Highway 401. The second route, route 201, runs from Conestoga College Doon Campus Door 6 in Kitchener to Conestoga Mall in Waterloo, primarily along Fischer-Hallman Road in both cities. The third, route 202, runs in a crosstown fashion through Waterloo, primarily along University Avenue, between the Boardwalk shopping centre and Conestoga Mall. The fourth iXpress route, route 203, opened on April 28, 2014. It runs from Cambridge Centre to Sportsworld Terminal. An extension of the 203 to Conestoga College is made during the AM and PM peak periods when classes are in session. The fifth iXpress route, route 204, began service in September 2015. The 204 iXpress runs from Ottawa and Lackner to the Boardwalk via Victoria Street, Highland Road, Ira Needles Boulevard and Downtown Kitchener.^[21] The 205 Ottawa iXpress opened on April 30, 2018, which primarily served northern Ottawa Street.^[22] and the 206 Coronation iXpress launched September 2, 2019, partially replacing route 52.^[23] The 200 was discontinued upon the launch of Ion service; the bus portion not converted to light rail now runs on route 302, branded as Ion Bus.

In April 2017, it was announced that the Ion and iXpress services would be closely integrated into a single system.^[24] In March 2018, nine new Ion buses were unveiled; initially they were used on local routes in Cambridge. They now operate from Fairway Station in Kitchener to the Ainslie Street terminal in Cambridge. These vehicles offer new features, such as more comfortable, high-back seats, free Wi-Fi and USB charging ports.^[9][25]

Buses and Ion fare machines accept cash and the EasyGo smart card; unlimited transfers are available for 90 minutes of travel following payment of a single-use fare. Monthly passes or a stored fare balance are loaded on the EasyGo card; this can be done online, at customer service desks, or at ticket machines. Specialized passes for corporate or school purposes are loaded on specialized smart cards.^[26]

The new EasyGO system on electronic fare cards was first made available on March 1, 2019, in anticipation of the Ion light rail launch.^[27] At Ion launch, this fully replaced an old system of paper passes (and accompanying photo ID) and paper tickets.

Routes are listed effective September 5, 2022. The following is a general summary of route services; for details, consult the official website. Routes numbered below 100 are local services, numbers in the 100s are express services (the only remaining of which is 110) in the 200s are iXpress service with the iXpress brand, and in the 300s are full rapid transit with the Ion brand. Routes marked + use smaller BusPLUS vehicles. All routes, excluding 79 make connections to major transit hubs.

In 2022, Grand River Transit announced that they had ordered six electric Nova Bus LFSe+ to their fleet, scheduled to arrive in spring 2023. An additional five electric buses will arrive in 2024.^[29]

One major transit terminal is operated and staffed, the Ainslie St. Transit Terminal at Galt City Centre in Cambridge. In downtown Kitchener, customer service functions come from an office at 105 King Street East, near Frederick station. No GRT services remain at the Charles Street Transit Terminal. ^[30]

All ION stations have customer help points and ticket machines; most are major transfer points, with Waterloo’s Conestoga Mall, Kitchener’s Fairview Park Mall, and the University of Waterloo station also having off-street bus terminals. Unstaffed off-road satellite terminals are also in place at The Boardwalk Station, Stanley Park Mall, Sportsworld, Sunrise Centre, and Cambridge Centre. An additional terminal at the Conestoga College Doon Campus is planned.^[31] Other significant transfer points include King Street/University Avenue, Holiday Inn Drive/Hespeler, Conestoga College-Doon Campus, and the Preston Towne Centre.
