York Region Administrative Centre Annex: Update to local residents

As you may know, construction of York Region’s Administrative Centre Annex will begin early 2017 at the corner of Yonge and Eagle streets in the Town of Newmarket. Located next to the Administrative Centre – York Region’s headquarters – the Annex building will create a civic campus within an established government district. The construction of the Annex will realize York Region’s long-term plan to consolidate a variety of community, health and courts services into one central, fully-accessible, modern facility.

  • 2016: Issue, approve and award tender
  • 2017-2020: Construction
  • 2020: Occupancy


  • Eight storey modern facility connected to the Administrative Centre with an enclosed bridge
  • 422,000-square-feet of office, courts and clinic space
  • Improved local access to services in one fully-accessible location
  • Environmentally-sustainable design 
  • Located along a major transit corridor with easy access to amenities and services
  • Aligned with the Town of Newmarket’s Secondary Plan for increased density along Yonge Street


Where will the Annex be located? The Annex will be located at the corner of Yonge and Eagle Streets immediately south of the Administrative Centre and west of the Doane House. Currently, a parking lot for York Region staff occupies the future location of the Annex – this lot will be decommissioned in November 2017. As communicated earlier this summer, a new parking lot for Regional staff is now being constructed on Eagle Street between McCaffrey Road and Peevers Crescent to replace the south parking lot.

Will York Region staff travel along Peevers Crescent from the new parking lot once built? Once complete in November 2017, residents can expect to see some York Region staff walking along Peevers Crescent to access the Administrative Centre until the Annex opens in 2020. Once the Annex opens, however, Regional staff will be advised to travel through the Annex and its enclosed bridge to access the Administrative Centre. At that time, pedestrian traffic on Peevers is expected to return to the current state.

How will parking on residential streets be discouraged? Through an internal communication campaign, York Region staff is being reminded to park only in the designated parking areas and not along residential streets. Together with the Town of Newmarket, York Region is committed to minimizing disruptions to our neighbours and encourages residents to report any parking infractions. If you have a parking complaint, you can contact the Town of Newmarket’s Customer Service department at 905-895-5193 or file it online.

What's the impact on snow storage? In years previous, York Region stored snow on the west side of the current staff parking lot on Eagle Street. With the construction of the Annex, snow will no longer be stored in this location and will instead be trucked offsite.

Will the tree canopy be preserved between the creek and residential properties? 
York Region is committed to preserving a naturalized buffer area between the Annex and our residential neighbours. The tree canopies between the creek and the backyards of properties on Peevers Crescent will be preserved.

How will the Annex consider the environment? A key consideration of the Annex’ design is its location in a flood plain. In consultation with Lake Simcoe Region Conservation Authority and project engineers, the flood plain will be modified to accommodate the Annex while alleviating downstream flooding issues through improved storm water management using bioswales, permeable paving, in-ground retention and water absorbing vegetation. The Annex’s environmentally-sustainable design will also feature green and reflective roofs, a green living wall and many other energy efficient features. The surrounding grounds will include landscaped gardens, tree preservation and planting, and increased site vegetation. In accordance with Regional Council’s direction, the Annex is designed to achieve a LEED (Leadership in Energy Efficient Design) Silver designation.

How will residents be kept informed of the Annex' progress? York Region is developing a comprehensive communications strategy to help ensure residents remain well informed of project milestones and highlights as construction progresses.
