Current Closure
On the advice of the Township’s legal counsel, the Millbrook arena was closed to all members of the public on the morning of Friday, October 18th. This direction was the result of our legal firm’s review of the results from the September 2024 air quality testing in the facility which was being conducted annually to build on the Designated Substance Survey conducted in April 2023 (see link - Designated Substance Report).
Despite the presence of mould being identified in previous facility reviews, the results of air quality testing conducted by Cambium Inc. and EMC Scientific Incorporated Laboratory Analysis in 2023 did not indicate significant risk in the air quality at that time.
However, when the sampling was carried out again in 2024, the results indicated a significant and concerning increase in the mould levels. In consultation with a specialist in environmental law, it was recommended that the facility be closed to the public at once until more comprehensive testing and analysis could be carried out.
December 16th, 2024 Report to Council: Mould Assessment Results and Required Remediation at Millbrook Arena
Building Condition
The Millbrook arena has had several engineering and structural reviews over the last 10 years. In 2019, there were a series of investigations into the condition of the various elements of the facility (see links #9, #10 and #11).
In 2014 there was an Arena Needs Assessment Report presented to Council. Despite the facility being classified as “very deficient” and requiring between $400,000 to $1,000,000 of improvements to keep the facility in working order for the next 5-10 years (see link 2014 Arena Needs Feasibility Study) there was no significant structural repairs or investment made into the facility.
All of the previous assessments and reports were provided to the Rethink Group in 2022 when the company began their work on the Vision 2035 – Strategic Plan for Parks and Recreation Strategic Plan update.
In Phase 1 of the Parks and Recreation Strategic Plan update, Barry Bryan Associates was hired to update their previous reviews of the facility in the summer of 2022. In this comprehensive structural review, an estimate and breakdown of the recommended construction and costs to address the current structural deficiencies to allow the continued use of the Millbrook arena was estimated at $5.2 million dollars (see link Dec 18 2023 Agenda).
These estimates were to address only the structural deficiencies and did not include any costs of improving the exterior of the building, or replacing the field turf in the facility (estimated at $150-350K), or any consideration of the cost(s) related to addressing the hazardous materials and substances that have been identified in the facility, including asbestos, mold and lead paint among others
Interim Temporary Use of Building:
At the April 1, 2019 Regular Council meeting the following motion was passed:
That Council direct staff to investigate possible uses for the existing Millbrook arena, in its current state, to generate revenue until the future of the facility is determined. (see report 9.4 from link April 1, 2019 Council Agenda)
From that motion, staff connected with a nearby lacrosse team that was interested in selling their used turf field if it could be installed in a facility where they could utilize it for games and practices and allow other user groups to use it at other times.
At the November 4, 2019 Regular Council Meeting (see link Council Agenda Nov 4, 2019) Council passed a motion that approved the conversion of the existing Millbrook arena to a non-ice recreational facility for the short term.
The in-door turf usage of the facility has always been communicated to the community and user groups as being a temporary, short-term use, while the plans for the park site were being carried out.
Parks and Recreation Strategic Plan Update
In March of 2022, the Township hired the Rethink Group to begin work on consultation for the Vision 2035 – Parks and Recreation Strategic Plan to chart the future of recreation in the Township and update the previous 2011 Parks and Recreation Master Plan. The process included a review of the existing parkland and recreation amenities in the Township, including the Millbrook arena, and to provide recommendations on the future needs of parks and recreation in the Township.
The work on the Vision 2035 - Parks and Recreation Strategic Plan was the focus on the first 2 phases of the consultant’s work.
Phase 1 – Background Study and Public Consultation
Phase 1 included a review of the Townships existing Parks and Recreation Plan and a full review of our existing parks and recreation amenities. Once that was complete, the Rethink Group created the content of the household survey and began the household survey and engagement with user groups and committees, as well as an in-person community forum on May 10, 2023.
The public consultation for Phase 1 included a public survey open to all residents in the community that was planned to be open for 4 weeks, but was extended by a few additional weeks (June – August 2023). There was also a user group specific survey that was shared to 29 user groups in the community, 25 of which provide responses. The consultant also had several meetings with different user groups to generate additional feedback, and engaged several committees including the Millbrook BIA, Municipal Revitalization and Heritage, Millbrook Valley Trails committees.
There was an extensive effort made by the consultant and supported by the Township to promote the public participation in the 2035 Vision Parks and Recreation Strategic Plan. There was a notice that the plan was being updated in the 2023 Tax Insert from the Township. In addition, the survey were repeatedly featured in the local newspaper and was promoted over 23 separate times on each of the Townships various social media platforms (23 posts on Instagram, 23 posts on X and 23 posts on Facebook). It was also promoted on screens and/or posters at Township buildings and featured prominently on the homepage of the Townships website.
Phase 1 also included a community forum on the evening of May 10, 2023, the results of which were a part of the presentation to Council in the June 5th report to Council (see link May10, 2023_Community Forum Event Summary). This community forum was promoted in the local newspaper, on the Township website and social media, and to all the user groups.
From all these efforts, the survey had responses from over 319 households, 24 of 29 community user groups, and three committees and the in-person community forum had 28 in-person participants as well as a few additional who attended the discussion virtually (see link Report Parks and Facilities 2023-03).
Council Decision on June 5, 2023
At the June 5th Regular Council meeting, the Rethink Group presented the findings and results of Phase 1 to Council (see link Report Parks and Facilities 2023-03). In the section of the report that pertained to Millbrook arena, the option to demolish and replace the Millbrook arena with a downtown community park was favoured by 82.5% of respondents in the survey and 75% of participants in the community forum (page 18 of the report). It was also the favoured option by all three of the committees that provide input.
Following the presentation, the following motion was passed by Council:
“That staff be directed to commence planning for the creation of a community park on the Millbrook arena lands; and
That the existing users of the Millbrook arena be permitted to use the existing facility in its current state, until the final plans for the community park are approved by Council, or that the facility becomes a health and safety concern; and
That Council’s direction be carried forward in Phase 2 of the Parks and Recreation Plan – Vision 2035.”
Phase 2 – Downtown Park and CMCC Lands
Building on the findings in Phase 1, Phase 2 of the project moved forward with preparing the long-term vision and goals for the new Parks and Recreation Strategic Plan and created options for both the development of the Millbrook arena lands and the remaining parklands behind the CMCC.
In October 2023, there were two community forums open to members of the public to discuss these topics and options for the parkland. These community forums received a similar promotion approach as in Phase 1, and one of the meetings was held on a weekend (October 21st) in an attempt to improve participation.
The feedback from these two community forums was combined to the Phase 1 information, and provided the content for Rethink Group’s Phase 2 presentation to Council at the December 18, 2023 Council Meeting (see link Dec 18 2023 Agenda).
Phase 3 – Design and Amenities for Downtown Park and CMCC
The Township is currently nearing the end of this final phase of the Vision 2035 – Parks and Recreation Master Plan update. For this phase, the Township is working with the firm Landscape Planning, who is taking all of the data and feedback from Phases 1 and 2 and all of the community forums and public input to date.
Landscape Planning will be presenting several conceptual designs for these two areas of parkland at an Open House on November 19th between 4 – 7 p.m. at the CMCC in the Community Hall room
Financial Summary of Current Temporary Usage:
Since installation of the turf field, there have been predominantly 2 - 3 different user groups in the facility. Below is a financial summary of the past two full years of rentals in Millbrook arena operations. The $52,153.22 combines the cost of purchasing and installing the used turf and installing a heating system that was required to enable the use of the facility during the winter months.

Since the turf was installed, almost all of the rentals of the Millbrook arena occur between the months of October - May. Over previous two full years, the facility was rented a total of 1,219 hours. Over the 30-week span when the facility is primarily used, the facility was rented an average of 20.3 hours per week.
It should be said, the facility was not expected to operate at a profit.
