Applications will be reviewed by a peer assessment committee and selected exhibitions will be presented at Corridor 45|75 in 2024 or 2025.

Ottawa is built on un-ceded Anishinabe Algonquin territory. The peoples of the Anishinabe Algonquin Nation have lived on this territory for millennia. Their culture and presence have nurtured and continue to nurture this land. The City of Ottawa honours the peoples and land of the Anishinabe Algonquin Nation. The City of Ottawa honours all First Nations, Inuit and Métis peoples and their valuable past and present contributions to this land.

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, framed, non-porous, not needing climate controls 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 architectural drawing); 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 encourages applications from individuals with lived experience and identity as a member of Indigenous, Black and other racialized communities, persons with disabilities, women and other equity-deserving groups. The City of Ottawa recognizes the Anishinabe Algonquin 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 Anishinabe Algonquin 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.

Peer assessment committee members are chosen based on their knowledge and experience, fair and objective opinions, ability to articulate ideas, and ability to work in a team environment.
