Cobourg Transit is a fully accessible community transit system that serves the Town of Cobourg, operating with a fleet of diesel buses. The buses are separated into two areas on the interior, the front having low floors with seating reserved for accessibility access if needed, and poles to help riders safely stand. The section behind the second door is raised by some steps, and being just seating without much open space.

Bus service is provided on two routes which meet every hour at the Northumberland Mall and the Rotary Waterfront Park bus terminal As a result of each route being operated by a single bus at a time, bus stops are labelled by the minute of the hour the bus is scheduled to arrive.^[3] These regular routes operate Monday to Friday from 6:15 am to 7:45 pm, Saturdays from 8:15 am to 6:45pm and Sundays from 8:45 am to 3:45 pm. There is also an inter-municipal shuttle service to Port Hope, which connects at the mall or Northumberland Hills Hospital with Port Hope Transit.^[4]

Cobourg Transit also offers a specialised service called WHEELS to let people who cannot use conventional transit still get around the town.

During the COVID-19 pandemic, the buses were outfitted with signage to indicate appropriate distancing, and only accept coins like toonies for physical payment.

The standard fare for the bus service is $2, $1 if making a transfer from the Port Hope shuttle. Cobourg Transit also offers various other payment methods, sold at Victoria Hall and the Cobourg Public Library, both near bus stops; these include tickets and bus passes. The town has no plans to implement Ontario's Presto card, and the after school pass is sold within secondary schools to students to promote active transport.

On April 19, 2021, Cobourg began a pilot project for demand responsive transport in the city of Cobourg,^[5] after a review was finished exploring financial optimisations for the city.^[6] The transport advisory committee made a plan based on the review to experiment with software developed by RideCo, the goal being to reduce operating costs and emissions, and to get as many people in the bus as possible.^[7] The new service would launch in between 2020 and 2022, and is now known to residents as Cobourg Ride. Originally, the service was going to assist with the operation of the regular transit, as suggested by a survey monitored closely by the review, however, the town appears to have redirected to full on demand service in the near future.

Currently, the Town of Cobourg has two active transit routes. Both routes have various stops within suburbs, nearby to schools, and by suburban shopping centres. Both routes share a stop at the Northumberland Mall and the terminal in front of Rotary Waterfront Park, and various stops along Division Street. Route 1 is characterised by its comprehensive coverage of midtown and downtown suburbs, with many stops around schools and important locations, before heading to various big box stores and the mall. Route 2 is less comprehensive, providing minimal suburb, school, and shopping coverage, while instead prioritising serving key locations, like the Cobourg Community Centre.
