Financial Relief Program - Extended until January 31, 2021 

Newmarket's Financial Relief Program is an extension of the preliminary measures that the Newmarket put in place in March to waive penalties and interest on the March and April property tax payments. The Financial Relief Program will include:  

  • No penalty and interest charges on property tax payments until January 31, 2021
  • No penalty and interest charges for late payment of water/wastewater bills until January 31, 2021
  • No penalty and interest charges for all Town accounts receivable including development agreements, leases and sponsorships until January 31, 2021

Penalties and interest will start accruing on February 1, 2021 and would be charged on outstanding balances as of February 28, 2021. The possibility of further extension is being considered as part of the 2021 budget deliberations by Council on December 7, 2020. 

This Financial Relief Program ensures fairness and equity and is coordinated with the programs being offered by other levels of government. Residents and businesses that are able to continue to pay are strongly encouraged to do so. This will help the Town to continue to dedicate resources to those most financially challenged by COVID-19 and to continue providing essential services like fire and emergency, waste collection and safe drinking water.

In addition to the Financial Relief Program the Town has a number of plans in place to support the community as a whole and particularly the most vulnerable in the community through a variety of programs and partnerships. The business community is also being strongly supported through the creation of the Business Assistance Concierge (BAC) program (a virtual business support and resiliency centre) and an overall Economic Resiliency Action Plan.
