Environmental Assessment Study
Derry Road and Argentia Road

Study Area

The Study

Peel Region is undertaking a Schedule B Municipal Class Environmental Assessment (EA) that follows the Municipal Class EA process. The study is looking at improvements to the intersection of Derry Road and Argentia Road in the City of Mississauga. The study area is shown on the map.

The needs assessment study shows that improvements are necessary to keep the intersection functioning well in the short and long term to 2031.

The Process involves consultation with the public and agencies on:

  • Road improvement alternatives;
  • Assessment of the possible environmental effects of any improvements; and,
  • Reasonable means to lessen any adverse impacts.

Problem and Opportunity Statement is developed to set a vision for the study direction and define the project scope. This study is looking at how to alleviate congestion and improve:

  • Movement of people, vehicles and goods through the intersection;
  • Safety;
  • Protection for vulnerable road users, e.g. people with disabilities, seniors;
  • Pedestrian and cycling facilities;
  • Access to transit;
  • Economic growth and planned development; and,
  • Existing natural environment features.

Alternative Planning Solutions were developed to address the problem and opportunity statement that include:

  • Signal timing improvements;
  • Travel demand management; and,
  • Infrastructure upgrades (e.g. sidewalks, trails, cycling facilities, transit).

The Preliminary Design (illustrated below) proposes the following improvements to benefit all users of the intersection:

  • Extension of existing sidewalks on the north side of the intersection;
  • Continuation of multi-use trail along the south side of the intersection;
  • A new westbound dual-left turn lane from Derry Road to Argentia Road;
  • A new northbound through lane on Argentia Road; and,
  • A new southbound through lane on Argentia Road.

To achieve the proposed improvements, there may be impacts to adjacent properties and utilities within the study area.
