The McCarthy Woods and Southern Corridor Info Session held on January 17th, 2026 at the Hunt Club Riverside Park Community Centre, focused on protecting McCarthy Woods, McCarthy Meadows, and the Southern Corridor from the proposed Development Reserve (DR) zoning pushed by the National Capital Commission (NCC).
The objective of the Info Session, co-hosted by the Ottawa South Eco-Action Network (OSEAN) and the Hunt Club Community Association (HCCA) was to show why these urban green spaces are worth protecting.
The event was organized on very short notice, in preparation for a City Council decision on zoning, following an approved Motion at the Joint Committee stage. More than 12 volunteers helped put the event together and there were several booths sponsored by the panelists organizations as well as the Ottawa Wildflower Seed Library.
The event was well attended with 70 participants, and standing room only, reflecting Ottawa residents’ love of their urban greenspaces and thirst for more information on this topic. The info session was followed by a guided sunset walk led by the Ottawa Field Naturalists Club.
Here are the highlights of the discussion:
Christine Johnson, President of HCCA, and the moderator of the event kicked off the discussion about the McCarthy Forest, McCarthy Meadows, and the Southern Corridor. She emphasized the collaborative effort of various environmental and local groups to protect these green spaces. She also outlined how the broader event would unfold including speaker presentations, followed by a Q&A for the Info Session, and a concurrent open house with booths, and guided sunset walk to wrap up the day’s activities.
Andrei Grushman, a Co-host and HCCA director, thanked attendees and speakers, acknowledging many HCCA members historical contributions protecting the McCarthy Woods area. He also provided details on the NCC’s push to change the zoning of these lands from green space to “development reserve” despite having recently identified them as worthy of on-going environmental stewardship. While the NCC has no expressed intentions to develop the McCarthy Woods and meadows, DR zoning would make this a foregone conclusion, and pre-empt the secondary plan for the Southern Corridor (at Merivale and Baseline).
Marianne Ariganello, OSEAN Co-host, and Riverside Park Community Association Director, spoke about the NCC’s lack of transparency regarding their plans to rezone the majority of greenspace in the McCarthy Woods and Southern Corridor area. She explained the changes were quietly introduced within the complex municipal rezoning bylaw review, which many residents were largely unaware of. She considered whether the NCC’s actions were motivated by the need to meet a $45 million savings target by disposing of these public lands. She called for a full, impartial, and transparent assessment of the lands’ suitability before any rezoning or potential development should take place. She emphasized the need to restore public trust in municipal and federal governments by acting in good faith.
Councillor Riley Brockington, currently serving his third term representing River Ward, provided an overview of the comprehensive zoning bylaw review process. He explained how the city’s official plan (approved in 2021 by council and 2022 by the province) precedes the zoning changes aiming to accommodate the projected growth of 400,000 to 500,000 people in Ottawa over the next 30 years. He spoke of other major changes beyond access to green space, such as increased density in neighborhoods near transit stations, and waiving mandatory parking requirements for development projects in urban hubs. He expressed support for more protective zoning for the McCarthy Woods and Southern Corridor than the NCC was pushing, and he emphasized the need for community-led solutions. He also urged developers to start building the 6000 housing units already approved for development by the City in River Ward.
Mireille Trent, an Environmental Economist and Butterflyway Ranger, expressed concern that Ottawa’s quality of life is “in jeopardy” due to the proposed sacrifice of urban green spaces. She found it hard to believe the NCC is pushing for “development reserve zoning” without thorough community consultations, seeing it as contradictory to municipal and federal environmental targets and policies (e.g. protection of Ottawa’s Tree Canopy, and Canada’s Climate Change and Land Protection Commitments). She highlighted that the proposed zoning in the McCarthy Woods and Meadows would affect 103 hectares of urban green space, emphasizing the health benefits of access to green spaces, as well as the well documented ecological value of these public lands. She called for open and transparent land-use decision-making based on the full range of quantitative evidence and qualitative information available.
John Sankey, a longtime Hunt Club resident and naturalist, focused on the importance of the McCarthy meadows as critical habitat for pollinators. He emphasized that “practically everything we grow…depends on insects to pollinate” and noted the significant decline in insect populations over the last 30 years. He explained “enhanced” meadows such as the McCarthy Meadows with a high diversity native plants and insects are crucial for a healthy ecosystem.
Bernie Muncaster is co-author of the 2005 Urban Natural Areas (UNA) study, which evaluated UNAs based on nine criteria, such as ecological diversity, representation of flora, and overall ecosystem health. He revealed the McCarthy Woods UNA scored highly with an average of 4.11 out of 5, placing it as the seventh highest-scoring area among the hundreds of assessed natural areas in Ottawa. He contrasted this with the CNR Woods UNA (143) in the same corridor which scored lower (2.22 out of 5), indicating it was at the low-end of the medium environmental value. The Leopold Woods UNA in Revelstoke was assessed as having a medium environmental value in this comprehensive study.
Jakob Mueller & Owen Clarkin both representing the Ottawa Field Naturalist Club as respected Ottawa Naturalists are very familiar with the McCarthy Woods and Meadows area. Owen Clarkin quickly highlighted the exceptional quality of McCarthy Woods, describing it as the “highest quality forest inside the city of Ottawa”. Jacob Mueller emphasized the increased maturity of the younger forests, and the discovery of additional biodiversity, including rare plant species, in this greenspace which has continued to naturalize and flourish since the UNA study was conducted 20 years ago. Both panelists underscored the crucial role of connectivity (of the greenspaces within the corridor, and of the woods and meadows) for the long-term health of green spaces. Jakob and Owen led the guided sunset walk following the Info Session.
Angela Keller-Herzog, President of Community Associations for Environmental Sustainability (CAFES), outlined her organization’s role tracking municipal environmental issues and supporting members in environmental advocacy. She encouraged community members to write personalized letters to MPs and the mayor noting that such efforts can have significant impact. She also recommended seeking “positive solutions” like land swaps or identifying alternative development sites with less ecological value that could be used for development purposes.
As chair of the Greenspace Alliance, Paul Johanis advocated for maintaining a “inner green belt” in Ottawa to connect various green spaces to serve the growing population. He stressed that access to nature is a human right and a public good and urged the NCC to adopt this broader vision.
Jane Moore, President of the Poet’s Pathway spoke about the significant green spaces that honor Canadian poets and connects communities and nature through a green necklace, with several jewels such as the McCarthy Woods and the Southern Corridor. She highlighted the historical and cultural importance of these urban greenspace, noting that the poets celebrated along the pathway consciously created a “national Canadian voice”. Jane Moore and Ben Glossop both expressed dismay that such a vital cultural and natural asset could be targeted for development.
The event concluded with a strong call for united community action to protect the McCarthy Woods and Southern Corridor given their environmental, cultural and other benefits, while also advocating for housing solutions that do not compromise existing valuable public green spaces. The audience was encouraged to continue engaging with local politicians and media outlets to amplify their message.
There was a lot of enthusiasm for continued protection of the McCarthy Woods and Southern Corridor by the Info Session participants from across Ottawa.
