non compliance noticeWhat You Need to Know About the By-law

The City of Markham limits outdoor water use in the summer. These limits happen between June 1 and September 30 every year. They apply to all residential owners, tenants, and lessees.

Here are the rules:

  • The City of Markham limits when you can use municipally-supplied drinking water to water your lawns, gardens, trees, and shrubs.
  • Outdoor watering on residential properties is allowed between 6 to 9 AM or 6 to 9 PM, but not both.
    • Properties with an even-numbered street address can water their lawns on even-numbered days during this time
    • Properties with an odd-numbered street address can water their lawns on odd-numbered days during this time
    • Those in violation of Markham’s Summer Water Restrictions (Water Use By-law 2019-53) may be fined up to $5,000 upon conviction.

Why Are Summer Water Restrictions Needed?

During summer months, water use more than doubles. The City needs to make sure that it has enough water to meet demand. By reducing how much water we use during peak hours (10 AM to 5 PM) we can help our infrastructure last longer. It reduces construction, operation, and maintenance costs. It also helps us lower the cost of providing reliable and safe water to our community.

Summer Water Restrictions Help:

If we reduce the amount of water we use during peak hours (10 AM to 5 PM), we prolong the lifespan of our current infrastructure and helps manage operational costs.

Maintain a Reliable Water Supply

A reliable water supply helps ensure drinking water reserves, adequate water pressure, and fire protection. By reducing our use of treated water during peak hours, water will be there when we need it.

The water used outdoors from sprinklers, hoses, and driveway car washing runs off into storm sewers on your street. It can pick up all sorts of pollutants along the way. Contaminated water that goes into our storm sewers flows directly into Lake Ontario without being treated. Reducing outdoor water use can reduce the pollutants that end up in our drinking water source. Plants, wildlife, and aquatic animals need a clean lake, too!

Non-Compliance Notices

The City actively looks for people who aren’t following the water restrictions. We hand out notices to residents that don't follow Water Use By-law 2019-53.


There are some exemptions to Water Use By-law 2019-53

  1. Properties with newly laid sod can use water for a period of 2 months after the sod is first laid.
  2. Properties not connected to the municipal water supply don’t have to follow these water restrictions. However, we do encourage all property owners to be good environmental stewards and follow the water use restrictions.
