Tile Drainage Area

Created for the purpose of OMAFRA having the knowledge of where agricultural field tile drainage has been installed and whether it was installed using a systematic or random design. This information also exists so that OMAFRA can validate whether the licensed contractors have met the conditions of their license.

Licensed agricultural tile drainage contractors create plans for numerous agricultural tile drainage systems and install thousands of feet of agricultural drainage tile each year. As a requirement of their license, each contractor must report to the Ontario Ministry of Agriculture, Food, and Rural Affairs (OMAFRA) the location of the area where they installed drainage tile. These areas are represented as polygon features.

Legislated or Legal Authority for Collection: Agricultural Tile Drainage Installation Act (Regulation 18)

Additional Time Period Information: The legislation was official as of 1983 but some the data holding may contain data that was installed prior to 1983. The legislation is still in effect therefore the data holding is still currently receiving information.
