A proposed zoning change at 400 Millennium Boulevard in Waterloo could bring additional single-detached homes to a planned residential community in the city's northeast end.

Activa Holdings Inc. has submitted a new rezoning application seeking permission to develop detached homes on two blocks previously designated for townhouses.

The property is part of a larger mixed-use development near RIM Park and Country Squire Road that received draft subdivision approval from Waterloo City Council in October 2025.

For homeowners, prospective buyers and anyone following new construction in Waterloo, here's what is planned, what's changing and what happens next.

What is planned for 400 Millennium Boulevard in Waterloo?

The development is located in northeast Waterloo, near the established Carriage Crossing neighbourhood and RIM Park.

On October 27, 2025, Waterloo City Council approved the draft plan of subdivision for a mixed-use community at 400 Millennium Boulevard, contemplating up to 634 residential units.

The broader development includes plans for:

  • Single-detached and semi-detached homes
  • Townhouses
  • Apartment and other multi-unit residential buildings
  • Commercial space
  • A public park
  • Stormwater management facilities
  • Conservation and open space

The original planning application identified a range of approximately 583–634 residential units.

The City's newer rezoning application identifies a range of 572–623 residential units across the entire property. The final number and configuration of homes may change as the development progresses.

What is changing in the latest rezoning application?

Activa's latest application, Z-26-18, proposes rezoning Blocks 6 and 8 within Draft Plan of Subdivision 30T-23401.

These blocks are currently zoned Residential Seven (R7), which permits townhouses under the applicable site-specific zoning provisions.

The developer is requesting Residential Five (R5) zoning to permit single-detached homes instead.

In practical terms, the proposed amendment would allow detached homes on two portions of the subdivision where townhouses were previously planned.

These proposed changes apply to Blocks 6 and 8. The broader subdivision continues to include a variety of residential housing types, along with commercial and community uses.

The new rezoning application is subject to the City's planning review process.

Why is this development worth watching?

New residential developments contribute to the evolving housing landscape in Waterloo, particularly in growing areas of the city.

For prospective buyers, the proposed change could introduce additional detached-home options within a future northeast Waterloo community.

For existing homeowners, development activity provides useful context about the types of housing being planned nearby, future neighbourhood growth and potential changes to the surrounding area.

However, a proposed zoning change does not automatically translate into new homes being built or made available for purchase.

Construction timelines, pricing and sales availability have not been confirmed through the municipal planning information reviewed.

New development does not, on its own, determine whether existing home values will increase or decrease. Property values are influenced by numerous factors, including buyer demand, comparable sales, inventory and broader market conditions.

Has the 400 Millennium Boulevard development been approved?

The broader subdivision received draft plan approval from Waterloo City Council on October 27, 2025.

The newer rezoning application affecting Blocks 6 and 8 is a separate proposal that remains subject to the applicable municipal review and approval process.

Draft plan approval is an important planning milestone, but it should not be confused with final subdivision registration or authorization to begin construction.

Additional approvals, servicing requirements and permits may be necessary before building proceeds.
