Deadline: Wednesday, May 13, 2020, 12:00 pm EDT

Information meeting: This event has been cancelled.

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 the fall of 2020 and in 2021.

Frequently Asked Questions:

How long is each exhibit timeslot?
Timeslots are approximately 16 weeks each, resulting in 3 shows per year. We also allot about a week in between shows for tear-down and installation.

Could the number of timeslots be affected because of the Coronavirus?
It is possible that the number of timeslots for the 2020-2021 season could be affected if shows from our 2020 season are postponed.

If I submit a proposal for the 2021 exhibition season at City Hall Art Gallery or Karsh-Masson Gallery, am I eligible to also apply for an exhibit at Corridor 45|75?
Yes, you can submit a proposal for both Calls; however, it is not guaranteed that the peer selection committee will select multiple proposals that have the same applicant for both Calls. Applicants who have exhibited at Karsh-Masson Gallery or City Hall Art Gallery within the last two consecutive years are not eligible to apply.

Please note that for each Call, only one submission per applicant is permitted (as opposed to per artist) so that artists can be involved in multiple proposals, but they can’t be the primary applicant on more than one proposal. For example, a curator can include artist A in their group exhibition proposal, and artist A can also submit their own solo exhibition proposal.

Would a sketch be helpful for the jury to see what I’m planning for the space?
Yes, a sketch would be helpful – however, if you include a sketch/layout of the space in your proposal, it would count as one of the 10 images (jpgs) you’re submitting.

Can I still send in my application by mail?
Due to COVID-19 we are encouraging applicants to apply using our online form only this year. Please let us know if you need help filling out the online form.

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. 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 diverse community, including people from diverse ancestries, abilities, ages, countries of origin, cultures, genders, incomes, languages, races and sexual orientations. 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 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 in your application is collected under the authority of the City Council approved Public Art Policy. Personal information will only be used for evaluating your application and administering the City of Ottawa Public Art Program. City of Ottawa employees and peer assessment committee members are required to treat both the content of applications and the deliberations of the committee as confidential.

2019 exhibitions

title graphic of the show: Transformations

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.
