These tiers have been slowly phased out, since Calgary Transit began expanding CTrain lines and capacity and implementing BRT service.

On April 27, 1985, a northeastern-bound line (Blue Line/Route 202) was opened, running from 8th St SW to Whitehorn station (just south of the intersection of McKnight Boulevard and 36th Street in the northeastern quadrant of the city), and on September 4, 1987, a northwestern-bound line (C-Line / part of Route 201) was opened in time for the 1988 Winter Olympics, running from downtown to University station (directly east of the University of Calgary campus, between 24th and 32nd Avenue on Crowchild Trail).

[20] Phase one of the North Central Line will travel from Eau Claire downtown to Shepard in the SE.

[21][22] On July 18, 2007, Calgary Transit officially unveiled a new red and white livery for its CTrain, articulated buses and every new bus or train coming into the system.

[23] On February 18, 2009, Calgary Transit celebrated the 1,000,000,000th rider, randomly selecting a passenger, Shelly Xiao during a ceremony at the 1 Street SW CTrain station.

[24] On August 30, 2004, Calgary Transit opened a bus rapid transit line to operate future CTrain routes (the D-Line and an as-yet unplanned northbound line), using conventional buses until articulated buses entered service on June 25, 2007.

Preliminary functional studies were undertaken – specifically for 17 Avenue SE (2010)[27] and the Southwest Transitway (2011)[28] – to explore the feasibility of major transit projects for the near future.

[30] This line was introduced after Calgary's Mayor promised to make the airport more accessible via public transit.

In December 2012, Council approved the RouteAhead Plan, which outlined the major transit projects the city would pursue for the next 30 years.

In order to make the new service unique from existing "BRT" routes, new stops now have heated shelters, real-time information, elevated sidewalks, and security cameras (for MAX Purple).

Community Shuttle, which provides scheduled local service with smaller buses, is currently made up of ARBOC Freedom vehicles.

Calgary Transit's 72 original style SD160s were delivered in three orders between 2000 and 2007 and have all since been retrofitted with Air Conditioning and the newer red and white livery.

[42][43][44] In June 2010, 38 new restyled Siemens SD160s, featuring factory equipped AC and various cosmetic and technical changes over the previous series, began to arrive.

Service frequency on the CTrain and busier bus routes is typically from 5–30 minutes with operating hours of about 5 am – 2 am.

[48] Occasionally sponsors allow for free travel across the network for one day, such as New Year's Eve 2023 which was funded by Toronto-Dominion Bank.

A transfer or proof of fare is valid for 90 minutes from the time of issue, for any transit service (including stopovers).

In cooperation with many of the post-secondary schools located in the city, a Universal Pass (U-Pass) program is offered to all students, paid as part of their tuition.

In June 2015, the City of Calgary decided to scrap the Connect Card project and attempt to recover costs from Schneider Electric (formerly Telvent).

[60] In summer 2020, after a year-long trial, Calgary Transit rolled out its MyFare app for mobile devices, based on Masabi's Justride platform.

Many citizens resent the fact that single-ride tickets, if not activated, expire 7 days after purchase date.

The main duties of a Calgary Transit peace officer are to protect the public using the system, its employees and its assets.

Officers must respond to requests for assistance from customers and employees which include arresting persons found committing criminal offences (indictable or summary conviction) on or in relation to Calgary Transit facilities, vehicles and property.

Other duties includes public education, regular patrols of the transit system, customer relations and issuance of violation tickets.

All officers are equipped with handcuffs, OC spray, collapsible batons and protective body armour.

Officers went through an intensive week-long training program through the internationally recognized Law Enforcement Bike Association (LEBA).

As with most agencies, PS&E utilizes its own radio service; and a centralized call taking and dispatch centre.

Running every 20 minutes during the morning and evening rush hours, the free service carried an average of just over 800 people per day.
