The City of Ottawa Public Art Program is now accepting exhibition proposals from local professional artists and curators working in all media. Applications will be reviewed by a peer assessment committee and selected exhibitions will be presented at Corridor 45|75 in 2022 or 2023.

About Corridor 45|75

Corridor 45|75 is located at the O-Train Line 1 (Confederation Line)’s Rideau Station on the west concourse near the Rideau Centre entrance. It is open every day; opening hours coincide with the O-Train Line 1 operating hours. It is wheelchair accessible and admission is free through the Sussex Drive and Rideau Street entrance. (Hours of operation are subject to change due to Covid-19 closures.) Exhibitions at Corridor 45|75 feature the work of local professional artists working in all media and include solo, group and curated exhibitions. Corridor 45|75 presents approximately 3 exhibitions annually.

Important note about the exhibition space

Corridor 45|75 is a unique exhibition space located in a high-traffic underground light rail transit station one level above the train tracks. It is not a pristine, climate-controlled environment and is therefore best suited to artwork that is protected or framed and can be easily cleaned. The display space is protected by tempered glass doors that are locked but are not airtight. Behind the glass windows, the exhibition area is one long continuous space. Sections B to F are programmable (refer to floor plan); sections A and G feature permanent signage and cannot be used as exhibition space. Site-specific exhibitions that engage with this unique space will be the most successful. Although Rideau Station has 24/7 security, gallery staff are not onsite daily therefore exhibitions must be self-sufficient and cannot require regular maintenance. Artists are strongly encouraged to visit Corridor 45|75 and familiarize themselves with the current conditions of the space prior to applying.

A public gallery is a forum for the exploration of diverse ideas. The City of Ottawa exhibits artwork in all media that are of interest and importance to the community, that foster a sense of who we are, and that reflect current artistic practices. These exhibitions are presented in the public domain allowing for an appreciation, understanding and interpretation of our past and present through gallery programming.

The City of Ottawa supports cultural activity that is inclusive of Ottawa's equity-deserving communities, including people from diverse ancestries, abilities, ages, countries of origin, cultures, genders, incomes, languages, races and sexual identities. The City of Ottawa recognizes the Algonquin Anishinabe Nation as Ottawa’s Indigenous Host Nation. The City of Ottawa is committed to supporting cultural activities that respond to the Calls to Action put forward in the Truth and Reconciliation Commission Report. Applications from Algonquin Anishinabe Host Nation, First Nations, Inuit and Métis artists and curators are welcome and encouraged. The City of Ottawa recognizes both official languages as having the same rights, status and privileges.

Personal information will only be used for evaluating your application and administering the City of Ottawa Public Art Program.

Transformations: 24 artists, 13 stations, 12.5 km

September 14, 2019 to January 5, 2020.

Public art exists in many forms and locations – from public facilities to streetscapes and pedestrian pathways. Art and transit create a dialogue through an exchange between the artist’s imagination and the public’s engagement.

The City of Ottawa Public Art Program commissions site-specific art through a one percent funding allocation from new municipal development projects. As part of this Program, the O-Train Public Art Program launched in 2012 with a series of calls to artists, including separate opportunities for Algonquin Anishinabe artists for Pimisi Station. Twenty-four artists were peer-selected to create artwork for 13 stations along 12.5 km.

The permanent artworks installed along the O-Train Confederation Line Stage 1 are a result of the artists’ multi-year creative processes and partnerships with community members, O-Train design team members and cultural collaborators.

This exhibition provides glimpses into each artist’s process, forming a guide to accompany you on your journey.
