TORONTO, May 13, 2026 – York Region announced on May 12 that, due to air valve and valve chamber replacement and upgrade work, some residents along Bayview Avenue in Richmond Hill will experience a temporary water shutoff from 10 p.m. on May 21 to 5 a.m. on May 22. For Chinese families in Richmond Hill, households with seniors, basement tenants, home daycare operators, and small businesses, failing to store water in advance or review the construction notice may mean only discovering the outage late at night or early in the morning, when they are unable to wash, cook, flush toilets, or complete cleaning tasks. York Region said the work will be carried out overnight in order to reduce disruption.
York Region said the project is part of a broader air valve and valve chamber upgrade program, with related work taking place in Markham, Richmond Hill, Vaughan, and Whitchurch-Stouffville. The specific outage in this case affects some residents along Bayview Avenue in Richmond Hill, with the interruption expected to begin at 10 p.m. on Thursday, May 21, and end at 5 a.m. on Friday, May 22.
This notice is especially relevant to three groups: families with babies, seniors, or sick relatives at home; newcomer tenants living in basements or shared housing; and small restaurants, home kitchens, and small businesses with high water needs. In real life, the most common problem is that residents may not fully understand the English-language notice or may assume an overnight outage will not matter much, only to realize early the next morning that they have no water. For families and businesses that need to prepare baby formula, care for a bedbound senior, wash dishes, or manage store sanitation on schedule, preparing in advance is more practical than reacting at the last minute.
York Region advises affected residents to store water before the outage, including preparing drinking water in large containers and filling sinks or bathtubs for other uses. After water service is restored, residents should run the cold tap for a few minutes to flush out any air trapped in the pipes. The region also says there will be more construction vehicles in the area during the work, but residential driveways and entrances will remain accessible.
At the same time, the posted outage time should not be understood as absolutely fixed. York Region says that while the interruption is expected to be short, if it lasts longer than planned, affected residents will be contacted directly and service will be restored as soon as possible. All construction projects may also be adjusted because of weather or other factors, and advance notice will be provided when possible. Residents and business owners should therefore leave some buffer in their schedules rather than assuming that cleaning, restocking, or caregiving can all begin immediately once water returns.
A more realistic example would be an elderly Chinese resident in Richmond Hill who usually goes to bed early and does not notice a message in the mailbox, on the front door, or in a neighbourhood group chat, and only realizes the next morning that there is no water. If family members help check in advance whether the home is within the affected area and prepare drinking water, water for washing, and basic cleaning water, that can reduce inconvenience late at night and early in the morning. Basement tenants should also check with the landlord or property manager in advance to confirm whether a notice has been received, rather than waiting until the tap runs dry.
Residents with questions can contact York Region at 1-877-464-9675; TTY users may call 711 and specify that the inquiry concerns the air valve and valve chamber repair project. Households with seniors, babies, or sick family members, as well as residents operating small restaurants, home daycares, and small businesses, should confirm before the evening of May 21 whether they are affected, store water in advance, plan cleaning and stocking schedules, and run cold water for a few minutes after service returns in order to reduce inconvenience caused by the outage, misunderstood notices, or timing changes.
