City of Mississauga Suggests Updates to the Public Tree By-law Tree

In a corporate report presented at General Committee today, staff from the City of Mississauga’s Forestry section provided an informational overview of the suggested updates to the City’s Public Tree By-law.

“Trees play a crucial role for cities like Mississauga by improving livability. They are essential for creating and maintaining a healthy community,” said Jodi Robillos, Director, Parks, Forestry and Environment. “Over the last few years, trees within the city have come under increased threat due to disease, invasive species, climate change and human-driven damage. Through the updated Public Tree By-law, the City continues to prioritize tree health and well-being because of the endless benefits they provide. The draft Public Tree By-law clearly outlines the Tree Protection and Preservation Standards that will guide the public, development community and City staff.”

The draft Public Tree By-law will protect more than 300,000 trees on City streets and parks and was developed in response to recommendations made in the City’s Future Directions Master Plan, Urban Forest Management Plan and Natural Heritage and Urban Forest Strategy. The revised draft by-law:

·         regulates the planting, maintenance and removal of trees on public property

·         provides greater clarity on by-law violations

·         references a public tree permit process 

·         allows the City to prosecute corporations or individuals who don’t adhere to the by-law.

“The City of Mississauga enacted its first Public Tree By-law in 1975 to regulate the planting, maintenance and protection of trees and shrubs on public lands. The existing Public Tree By-law is outdated and no longer meets current standards,” said Brent Reid, Manager, Forestry. “The updated standards lay out the City expectations relating to tree protection on all projects that involve City-owned trees including tree protection fencing, securities and replacement requirements.”

Updates and improvements to the protection of City trees include:

·   Prohibiting storage of material, equipment or anything that would impede the health of a tree’s root zone

·   Requiring approval for work within the tree protection zone as identified and approved by City staff and prohibiting grade changes in the tree protection zone

·   Prohibiting dangerous liquids, gaseous or solid substances to come into contact with the tree’s root system

·   Prohibiting the removal of any woody debris that has fallen or been cut down by the City in a natural area and left

·   Prohibiting planting of trees on public land. In the event trees are planted on public land, the by-law stipulates that the subject tree becomes public and subject to the terms of the draft by-law

The draft Public Tree By-law would also introduce new permit fees for work that may impact City-owned trees.

Both the City’s draft Public Tree By-law and the Private Tree By-law will undergo community consultation this summer. Stakeholders will be asked to provide feedback about the new updates for the Public Tree By-law and submit feedback about what they would like to see changed in the Private Tree By-law.

Learn More About Parking Regulations and How They Affect You

Mississauga is made up of different neighbourhoods. How people live, work, play and move can vary across these neighbourhoods. So it follows that parking requirements for new construction and new businesses should not be one-size-fits-all. Demographics and preferences have also changed over the years, as has the demand for private parking.

Parking plays an important role in city building. It can shape how buildings are designed, how residents move and the way businesses evolve. The City of Mississauga is updating its off-street parking regulations under its Zoning By-law. Off-street parking refers to the amount of vehicle or bicycle parking that is required on private and public properties as a result of new development, redevelopment or a land use change. It does not apply to existing buildings, homes, street parking or municipal parking lots. 

Parking is expensive to build and maintain. By updating the regulations for private parking, the City can support housing affordability, enhanced development and economic opportunities and offer more mobility options that can help lower carbon emissions.

The City has launched its Parking Regulation Study to provide an updated framework to support future parking regulations. On Monday, May 31 at 6 p.m., City staff will present a draft report to the Planning and Development Committee that provides background research, draft policy directions and proposed vehicle and bicycle off-street parking regulations.

Meeting participants will have the opportunity to ask questions and share their feedback about the proposed changes. Watch the live meeting while it’s in session by viewing the livestream.

Starting June 1, residents and business owners can also view our online on-demand community meeting and provide comments.

The Parking Regulations Study is a key action from the City’s recently-approved Parking Master Plan and Implementing Strategy (PMPIS). It is also implementing key actions from the Transportation Demand Management (TDM) Strategy, 2018 and bicycle parking requirements in the City’s Zoning By-law noted in the 2018 Cycling Master Plan.

Culture Lives Here – Have Your Say on Creating Vibrant Cultural Districts within Mississauga

What cultural opportunities would you like to see in Mississauga? With a growing arts, culture and creative industry scene and unique neighbourhoods that are emerging as popular hubs of creativity and innovation, Mississauga is well-positioned to be an arts-friendly city. Many neighbourhoods in Mississauga are intensifying and we are witnessing a growing cluster of arts and culture facilities, and diverse entertainment, retail and dining options. The City will build on these existing assets and support the growth of these neighbourhoods as distinct Cultural Districts through new cultural infrastructure and unique programming.

Mississauga has identified six Cultural Districts, each with its own unique identity and community priorities, under its Cultural Districts Implementation Plan:

  • Clarkson 
  • Cooksville 
  • Downtown Core 
  • Malton 
  • Port Credit 
  • Streetsville 

Starting in May, you can complete an online survey to share your feedback on the Cultural Districts Implementation Plan and ideas for future activities in the Districts. Your input will help inform the development of arts and culture spaces and opportunities and help the City map out the first phase of implementation in the Districts. Many exciting things can happen in the Districts (e.g. public art, public space improvements, street festivals, pop-ups, performances, patios) and we want to hear from the community.

Benefits of Cultural Districts

Cultural Districts play an important role for the city. They offer residents and visitors alike a diversity of experiences within a distinct, concentrated mixed-use area. Cultural Districts help strengthen the local economy, create a sense of place and support community well-being, and deepen local cultural capacity. The six cultural districts will provide opportunities for the City to attract visitors, support local businesses, increase arts and culture and create vibrant neighbourhood hubs. Major benefits of Cultural Districts include: 

·         Creating opportunities for participating in arts and culture activities

·         Enhancing and beautifying public spaces and streets

·         Celebrating the unique local character and heritage of a neighbourhood

·         Providing new avenues for social interaction and community gathering

·         Encouraging and supporting economic development and business growth

·         Supporting the growth of creative industries and cultural production

·         Addressing needs of specific neighbourhoods

·         Boosting local tourism and the evening economy

·         Preserving and reusing historic infrastructure, buildings and landmarks

·         Connecting people to outdoor spaces (e.g. parks, open spaces)

In February 2021, Council approved the Implementation of Cultural Districts, which are a key recommendation within the Culture Master Plan.

Have Your Say – Does Mississauga Need an Apartment Building Standards and Maintenance Program?

Mississauga has a number of property-related by-laws that detail the requirements for maintaining rental apartment buildings and other properties across the city. Staff are currently assessing the need for an Apartment Building Standards and Maintenance Program similar to the City of Toronto’s RentSafeTO program. 

The proposed program could include a proactive rental building inspection plan.

Anyone with an interest in rental apartment building standards and maintenance can share their experiences, thoughts and ideas by visiting the public engagement website to ask a question and take the online survey.

The input received will help determine the need for a standards and maintenance program for rental apartment buildings in Mississauga.

The online survey is available until July 31, 2021.


The Ontario Headwaters Institute and our partners in the Credit Headwater Alliance urge all those downstream of Erin and/or who care about sound watershed planning to sign the petition below to support a federal impact assessment of the proposed sewage treatment plant in Erin, Ontario. We also ask you to copy and forward the petition to your local mayor, councillors, and MP. Please take whatever action you can by May 24.


Much of the land close to Lake Ontario is built up, with reduced natural heritage and poor inland water quality. Now, increasing development is charging in to our headwater areas where, unless properly planned, it may overwhelm our smaller streams and push the upland reservoirs upon which the health of many of our degraded watersheds now depend past numerous tipping points. The assault is multi-pronged, and a few issues include:

  • Land use planning that lacks a lens for sustainable communities, buildings, and homes;
  • Thirty-year targets for development lands and 400 series highways in the Greenbelt that drive prices up and farmers away;
  • Provincial policies that expedite virgin aggregate extraction over natural heritage, farming, conservation, and recycling;
  • An absence of cumulative monitoring and reporting – even where required when fundamental land use planning acts are amended; and,
  • Municipal debates about growth, commerce, and taxes, with almost no thought as to where the excrement is going.

Many of these issues are being brought to bear in a proposed development in Erin, in the Upper West Credit River. One in particular revolves around the last bullet above: a proposed sewage treatment plant (STP) that is the cause of concern by many local residents and organizations, as well as provincial organizations. Key issues are that the temperature of the effluent from the STP may kill the local brook trout and that those living downstream were not adequately consulted.

To date, local groups and a federal MP have been very effective in seeking a federal impact assessment of the proposed sewage treatment plant. Efforts have included:

  • A petition to the House of Commons to seek a federal impact assessment of the STP. This petition was initiated by local resident Jenni LeForestier, was supported by conservative MP Kyle Seeback, and has obtained more than 1,700 signatures. You can see this petition at Petition e-3194 – Petitions (;
  • A request to the Impact Assessment Agency of Canada (IAAC) and the Minister of the Environment and Climate Change to conduct a federal impact assessment assessment, sent by five local and provincial organizations forming the Coalition for the West Credit River. The request can be found as reference number 81434 on the IAAC website, at Erin Wastewater Treatment Plant Project – (; and,
  • One member of this group alone led the creation of a petition that has attained more than 21,000 signatories to protect the Credit from the effluent from the proposed sewage treatment plant.

How You Can Help

With just a over a week until the federal government releases its decision on May 26 about doing an impact assessment of this inadequate and harmful sewage treatment plant, we urge anyone to speak out in favour of a full impact assessment,. This includes not only individuals, organizations, and municipalities downstream of Erin, but also anyone who cares about the link between headwater and watershed health. Please:

Thank you,

Andrew McCammon

Text of the petition for your convenience, which you can amend as you wish and send to local officials

I write seeking your support for a federal Impact Assessment of the proposed sewage treatment plant in Erin, Ontario, IAAC file 81434. The reasons are straight-forward:

  • Temperature of the Effluent: The temperature of the effluent from the proposed sewage treatment plant (STP) will be such that it may increase the temperature of the West Credit to a point that will impact the local brook trout, and in particular disrupt their breeding cycle, leading to their extirpation (local extinction);
  • Volume and Velocity of the Effluent: The proposed STP and new additional stormwater run-off appear to add volumes of water and increase stream velocity in the Upper West Credit. This may impact the stability of the stream banks, reduce riparian cover, and alter the stream bed. Outcomes include damage to local property and increased erosion, with the deposition of the eroded material downstream potentially impacting other regionally significant aquatic species;
  • Virtually No Consultation with People Living Downstream nor First Nations: Ontario environmental assessments require public consultation. In the case of the Erin STP, local consultation was sporadic, and consultation with both those living downstream and First Nations were virtually non-existent; and,
  • Impacts excluded under Provincial Rules: The pipe carrying the effluent from the Erin STP is mostly in Ontario’ Greenbelt, as is the location where the pipe will disperse its effluent into the West Credit River. While the Greenbelt Plan allows infrastructure within the Greenbelt, the Plan does not require any environmental assessment of the impact of that infrastructure. It is thus imperative that a federal assessment be commissioned to assess the impact of the effluent on the West Credit River.

To address these short-comings, the proposed STP in Erin needs a federal Impact Assessment.

Thank you for your consideration,
