Latest Update: April 2026

What is Tewin?

Tewin is a proposed new community near Carlsbad Springs, envisioned as a sustainable, inclusive, and transit-oriented development rooted in Algonquin values. It is 800 gross hectares in size (445 net developable hectares) supporting a proposed population of at least 35,000 people. The project is a partnership between the Algonquins of Ontario (AOO) and the Taggart Group, with Caivan as another significant property owner. The changes to the City’s official plan to include the Tewin lands took place in November 2021. Central to the inclusion of Tewin to the urban area is the principle that “Tewin pays for Tewin” as referenced in Annex 10 and 12 of the Official Plan.

What needs to happen before the land is developed?

Tewin, like all other urban expansion areas, needs to go through a secondary planning process supported by a variety of technical studies to guide future development.

Tewin community planning process is proceeding through the Integrated Planning Act application and Municipal Class Environmental Assessment (EA), combines the Planning Act approvals and Municipal Class Environmental Assessment (EA) requirements for municipal infrastructure such as roads, water, wastewater, and stormwater systems. The Secondary Plan, supporting studies as well as financial implementation will need to go to Planning and Housing Committee and Council for approval.

Projects of this scale typically take 3-4 years to get through these planning stages.

Public Engagement

To date, several engagements have taken place including 3 formal public open houses. The latest one took place in January 2025 – here is a link to the information that was shared at that time: Tewin Community Design Plan and Secondary Plan | Engage Ottawa. The developer maintains a website and newsletter to provide updates on the development. Information can be found at tewin.ca.

To ensure collaboration and information sharing with local stakeholders, the Tewin Community Advisory Committee (TCAC) was formed. TCAC will next meet on April 8th, 2026 to receive an update on the project. This will be my first meeting with the committee. We will review what came out of the last open house, updates on the planning work progress since that time and discuss an approach for the next public open house, which is tentatively planned for April 28, 2026. 

The Carlsbad Springs Community Association receives updates and notifications on Tewin and shares them with the community through their communication channels as well.

I will keep this page dedicated to updates on the project.

Motion raised in October 2025

In October 2025 a motion was brought forward by the Bay Ward Councillor at Planning and Housing Committee to remove the Tewin development from the official plan. While I am not a member of the Committee I provided my views alongside residents and other stakeholders regarding the motion. The motion did not pass.

My public statement was as follows: Throughout my campaign I was clear that I will not support any motion brought forward by urban councillors that aim to interfere with developments in Osgoode Ward 20. Also, I do not believe the motion is written in a way that reflects our interests for the following key reasons:

• It frames investments in rural infrastructure as a waste of taxpayer dollars – this argument cannot stand as it threatens other rural infrastructure spending, spending which is much needed given 80% of Ottawa is geographically rural.
• I think it is inappropriate for municipalities to interfere in indigenous politics and for City Councillors to cherry-pick descenting voices when it supports their cause.
• I disagree with relitigating past decisions made by Council – I do not believe people elect officials to continue to re-vote on the same issues when they are not happy with the result. This creates an unpredictable environment for businesses that rely on these approvals to operate and makes Ottawa a more expensive and less desirable place to do business.
• The motion opens the door for land-use and planning to be influenced by non-local stakeholders outside Ontario. This doesn’t align with the interests of local residents and landowners.
• The total removal of this project at this stage would cost the City millions of dollars in legal costs, bring us back 4 years in housing development planning and put pressure on the City to find development lands for 15,000 new homes to make-up its obligations to the province.
• The motion mis-characterizes the public costs of the project. The costs for the development itself are borne by Tewin, as was promised when the development was added to the official plan. Public costs to support this project are estimates only and they have not yet been voted upon.
  
  

Let me be very clear on this – residents in Carlsbad Springs have real concerns about this development and I am committed to ensuring their views are heard throughout the development process. This is a complex 25 year+ development project that requires time and consultation with the community to get it right. Should this project prove unviable or put at risk the interests of residents, I will be first in-line to put forward a motion to address the issue.

Where are we now?

I have received several briefings from City staff to better understand the project and the work underway. I have asked City staff to also communicate the staging of the works and to breakdown what options residents could have to improve their services and at what costs. That information follows:
