Leamington mayor Hilda MacDonald says that By-law 41-22, The Greenhouse Light Abatement Law, balances support for the economic growth of the  greenhouse industry while protecting the quality of life of  residents. The by-law passed on June 14, 2022 but allows some time for growers to comply.


The By-law includes the following provisions:

• Sidewall and endwall curtains must be installed and remain closed.

• Until the date that is the earlier of October 1, 2023, or the date that a greenhouse owner has installed all required curtains, lights may be on until 10:00 PM.

• As of October 1, 2023, ceiling curtains must be installed and closed in accordance with the provisions of the by-law.

• As of October 1, 2022, greenhouse owners who have not installed ceiling curtains must provide proof of purchase of the same.

• The specific time of day for curtain closure is included rather than referring to sunrise and sunset.

• Specific times of day to allow for gapping of ceiling curtains, up to 10 per cent, have been included

“We are proud to work closely with our community, OMAFRA and the municipality’s administration to get to the most-right outcome for everyone,” said George Gilvesy, chair of OGVG’s Board. “A big thanks to Chief Administrative Officer Peter Neufeld, Mayor Hilda MacDonald, and town council for their continued communication and taking the time to get this right. This kind of collaboration sets us on a path for greater prosperity and well-being across the community and the region as a whole.”
