Decision summary

On March 12, 2026, the Minister of Municipal Affairs and Housing made a Minister's Zoning Order in the City of Toronto as Zoning Order 005-2026. 

Decision details

A Zoning Order, made pursuant to clause 47(1)(a) of the Planning Act, regulates the use of the land and the erection, location and use of any building or structure on the land. The Zoning Order was requested by the Minister of Economic Development, Job Creation and Trade in order to safeguard the continued operational viability of Sanofi Pasteur Limited’s (Sanofi) biomedical manufacturing facilities and headquarters.

Zoning Order 005-2026 applies to the lands located at 1875 Steeles Avenue West in the City of Toronto. The subject lands are approximately 1.28 hectares in size and are located at the south side of Steeles Avenue West, near the southeast corner of its intersection with Dufferin Street. The subject lands are currently occupied by a 4-storey residential apartment building.

Zoning Order 005-2026 restricts the heights of all buildings and structures on the subject lands to a maximum of 33 metres.

This Zoning Order made pursuant to clause 47(1)(a) of the Planning Act was posted for consultation as a regulation. Bill 60 received royal assent on November 27, 2025, and therefore this Order is not a regulation and will not be filed with the Registrar of Regulations. The Order came into effect upon signing by the Minister of Municipal Affairs and Housing.

Section 47 of the Planning Act provides a process for requests to amend a zoning order to be submitted to, and considered by, the Minister. Any requests to amend this Zoning Order would be considered in accordance with the Act, including balancing provincial interests such as increasing housing supply, protecting jobs and supporting economic development.

Effects of consultation

All comments received were taken into consideration prior to a decision being made. 

The proposal received comments from the public, several industry associations, local housing advocate organizations, local landowners and the City of Toronto. 

There were comments received in support of the MZO from Sanofi Pasteur, industry associations (Life Sciences Ontario, Canadian Manufacturers and Exporters, Innovative Medicines Canada, Toronto Board of Trade and Toronto Industry Network), the City of Toronto and members of the public.

Sanofi Pasteur raised noise and security concerns that would lead to land use compatibility issues that would negatively impact the ongoing and future operation of the biomanufacturing facility and supported the MZO to protect against these impacts.  The industry associations raised the need to protect for strategically important employment lands to sustain existing manufacturers and to provide support for future investment.  The City of Toronto provided a Council resolution that endorsed the MZO to protect the long-term operational viability of Sanofi.  Members of the public noted Sanofi pre-existed the proposed developments that surround it and that they operate a key role in making life science products for the public (e.g. vaccine production). 

There were also a number of comments received in opposition to the MZO from the affected landowner at 1875 Steeles Avenue West, a neighbouring development proposal at 1881 Steeles Avenue West, the University of Toronto, two local housing advocate organizations (Federation of Rental Housing Providers of Ontario, Housing NowTO, More Neighbours Toronto) and a few members of the public.

The landowner of 1875 Steeles Avenue West noted the completion of studies accepted by city planning staff to show that noise or security compatibility issues were able to be appropriately mitigated with no impacts to Sanofi’s operations and opposed the MZO.  The neighbouring landowner noted they had a similar development proposal and echoed the concerns of the owner of the subject lands that any land use compatibility impacts on the Sanofi facility can be appropriately mitigated.

The University of Toronto noted that the Sanofi site had originally been part of the neighbouring UofT campus, and the university has successfully coexisted with Sanofi for over 50 years and any height restrictions applied to the university lands would have significant impacts.  Housing advocacy organizations noted their support for city staff’s position that more housing can be provided while adequately mitigating impacts on Sanofi. Members of the public expressed concern that the creation of much needed new housing would be held back by operational concerns of a private company.

Why consultation isn't required

Part II of the Environmental Bill of Rights Act, 1993 does not apply to proposals to make a Minister’s Zoning Order (MZO) under subsection 47(1) of the Planning Act, or to amend or revoke an MZO under subsection 47(8) of the Planning Act.

Although not required, the ministry is providing public notice of this request for consultation.
 

Proposal details

A Minister’s Zoning Order (MZO), made pursuant to clause 47(1)(a) of the Planning Act, regulates the use of land and the erection, location and use of any building or structure on the land, and prevails over the existing municipal zoning by-law to the extent there is any conflict.

The Minister of Economic Development, Job Creation and Trade (MEDJCT) has requested an MZO in order to safeguard the continued operational viability of Sanofi Pasteur Limited’s (Sanofi) manufacturing facilities and headquarters at 1755 Steeles Avenue West.

The MZO request proposes that all buildings and structures on the subject lands at 1875 Steeles Avenue West be limited to a maximum height of 33 metres.

In addition to the MZO, the ministry would be considering other planning tools that may be needed to protect the Sanofi facility from encroachment of non-employment uses and development on adjacent lands, given its strategic importance to Ontario, and would consult on those measures as appropriate.

To help ensure decisions are made in a transparent manner and support government priorities, the Ministry is seeking feedback on whether this request should be considered and any additional information that may help inform a decision. In particular, any potential environmental risks, financial impacts on the municipality or implications for other approved developments and how these can be mitigated.
