Regional Councillor Alan Ho

John Street west bound closed between July 17th and August 11th, 2023 .......

John Street will be closed on the west direction between July 17th and August 11th, 2023

The work will consist of a replacement of a cast iron pipe through the valley adjacent to the Pomona Valley Tennis Club.

The residents on Baywood Crt, Candice Gt and Julia St will have to detour to Proctor or Royal Orchard, and come back around to their residence. Signs will be posted identifying the detour route during the construction phase. What the City learned during the previous emergency job in 2020 is that when local traffic was allowed to access the area from Bayview, there were excessive vehicles that would follow those cars into the courts, which then would have to turn around, causing a log jam of vehicles and also a safety concern to any local pedestrians. Cars would also drive through the construction zone.

PRESS RELEASE - Thornhill All Candidates Meeting

Thornhill Municipal All Candidates Meeting – Thursday, October 13th, 2022

(Thornhill, Ont. October 13, 2022): Thornhill residents will have an opportunity to meet and ask questions of the registered candidates running for office in the upcoming October 14 to 24 Markham Municipal Election.

Organized and hosted by Aileen-Willowbrook Residents Association and Ward One (South) Thornhill Residents Inc., the Municipal All Candidates Meeting will be held as follows:

Date: Thursday, October 13
Time: 7:15 pm. Doors open at 7:00 pm
Location: Thornlea Secondary School, 8075 Bayview Avenue, Thornhill

Thornhill is one of the southern York Region’s fastest growing communities facing unprecedented urban intensification and population growth.
The Province’s Places to Grow legislation, TOCs and MZOs, has created a tremendous burden on municipalities struggling, with minimal funding sources, to provide and meet essential infrastructure needs and services for a growing population.

Healthcare and timely access to medical services and treatment is a serious concern with many new residents unable to find a family doctor accepting new patients. With an increase in population it will be even more difficult to get a family doctor increasing demand on ERs.

Traffic gridlock is an escalating problem that continues to worsen, even with the Yonge Street Subway extension that is going under people's houses against the residents' wishes to keep "Yonge Street on Yonge".

All Thornhill residents are welcome to attend the Municipal All Candidates Meeting, ask questions and let their voice be heard by the candidates.

The All Candidates Meeting is organized and sponsored by the Ward One South Thornhill Residents Inc and Aileen Willowbrook Residents Association. The two residents associations together with other residents groups cover more than 10 000 households between the Yonge Street and Leslie Street area of Thornhill. They successfully worked with the Council of Markham to have the Shouldice Lands protected as a park .
