This dataset contains a list of drainage superintendents who are appointed by the local municipality to manage drains constructed under the [Drainage Act, 1990](https://www.ontario.ca/laws/statute/90d17). Drainage superintendents are businesses or individuals that represent the local municipality to assist landowners to resolve their drainage concerns using the Ontario Drainage Act, 1990. This list is maintained by the Ministry of Agriculture, Food and Agribusiness (OMAFA) and includes municipality names, addresses telephone numbers, and superintendent contact information. This list is updated annually or as required throughout the year. More information about the work of drainage superintendents can be found at [Drainage Superintendents Association of Ontario (DSAO)](https://www.dsao.net/).

This dataset contains a list of soil erosion control contractors in Ontario who offer design and construction services to landowners to help control soil erosion on agricultural land. The list is maintained by the Ministry of Agriculture, Food and Rural Affairs (OMAFRA) and includes contact names, business names, addresses and telephone numbers. The list is updated annually in April. These contractors hold a valid Certificate of Achievement from OMAFRA. Holders of the Soil Erosion Control Contractors Certificate of Achievement have attended formal training developed and delivered by OMAFRA and have passed an examination that tests their skill and knowledge in the area of design and installation of select soil erosion control structures such as grassed waterways, water and sediment control basins (WASCoBs) and rock chutes. More information can be found at [Soil erosion control contractors certificate holders](https://www.ontario.ca/page/soil-erosion-control-contractors-certificate-holders).

The Agricultural Resource Inventory 1983 (ARI 1983) dataset includes agricultural land use and drainage systems information. This dataset evaluates the mix of crops and classifies them into different categories which are valid over a long period of time. Mapping these systems provides an overview of the location, quantity and quality of the use of agricultural land in southern Ontario. Used by farmers, land use planners, municipal officials, policy makers and the general public. This dataset is no longer collected or maintained. Information and data held by the Ontario Ministry of Agriculture, Food and Rural Affairs for this record is historical.

Get consolidated soil data mapped on a county basis in a digitally stitched and standardized product. This soil survey data was mapped by a number of soil surveyors from the 1920s to the 1990s. The product incorporates soil information from a variety of map scales. The project has brought the individual county or regional municipality surveys together to reveal inconsistencies in soil data across county boundaries. The soil complex database contains other descriptive information including: * slope class * Canada Land Inventory (CLI) ranking * stoniness * drainage class * texture

This dataset contains a list of licensed tile drainage contractors in Ontario who design and install agricultural tile drainage systems. These contractors hold a valid business license under the [Agricultural Tile Drainage Installation Act, 1990](https://www.ontario.ca/laws/statute/90a14) from the Ministry of Agriculture, Food and Agribusiness (OMAFA). Contractors with a business license must employ a licensed Class “A” machine operator and have licensed tile drainage machinery. Licenses are renewed annually (expire March 31), and the list is updated annually. The list is maintained by OMAFA and includes company names, contact names, addresses, telephone numbers, and emails.

This data identifies all provincially licensed abattoirs, abattoirs that conduct further processing, freestanding meat plants, and plants that specialize in the slaughter of the following animals across the province of Ontario: * alpaca, llama * beef * buffalo, yak * deer, elk * emus, ostrich, rhea * goats, lamb, sheep * pigs * veal, light calves * chicken, fowl * ducks, geese * fancy poultry * rabbits * turkey A map showing all provincially licensed meat plants in Ontario is also [available](https://experience.arcgis.com/experience/eb4cf68117cd4cada4d1ef78b6560fac). For more information on meat inspection in Ontario, please visit the Ministry of Agriculture, Food and Rural Affair’s [website](http://www.omafra.gov.on.ca/english/food/inspection/meatinsp/m-i-p-r/meatinspecprogram.htm). Each dataset contains the following data: * plant name * plant number * contact information * latitude and longitude coordinates * animal class

Get the locations of drainage tiles installed by licenced agricultural drainage contractors. As a requirement of the license, each contractor must report the location of new drainage tile areas to the Ontario Ministry of Agriculture, Food, and Agribusiness.

This data keeps the Ministry of Agriculture, Food and Agribusiness' records of modified or newly constructed drainage systems current. Constructed drains include ditches, buried tile systems, or natural watercourses that have been modified to improve drainage.

The Acidic Precipitation in Ontario Study (A.P.I.O.S.) was established in 1979 by the Ontario Ministry of the Environment to protect the environment from the detrimental effects of acidic deposition and determine the effects of acidic deposition on terrestrial ecosystems. The effect of acid inputs on the environment depends on the quantity and acidity of atmospheric inputs, and the buffering capacity of the terrestrial and aquatic ecosystems. The effect of acidic precipitation on soil is potentially significant because the soil is the reservoir of plant nutrients and the source of much of the water for aquatic systems. Changes in the soil's chemistry may therefore be reflected in both the terrestrial and aquatic environments. Information on the effects of acidic precipitation on soils is available from effects near point sources of pollution, from experimentation with simulated rain solutions, from natural changes observed in soil over time, and from models and soil forming theories. Anticipated effects of soil acidification include: reduced pH, leaching of basic cations (such as magnesium and calcium) and other exchangeable plant nutrients, reduction in base saturation and cation-exchange capacity, mobilization of soil-bound metals such as aluminum, and changes in biological activity such as decreased nitrification and soil respiration. The principal objective of the baseline program is to establish a uniform data base for soils across the province. This data base * provides current data to identify future trends, * enables the development of laboratory experiments which define soil sensitivity criteria to acidic precipitation, and * provides information required for sensitivity mapping of soils throughout Ontario.

Get the locations of dairy plants registered by the Ontario Ministry of Agriculture, Food and Rural Affairs.  The intended use of this data is to assist the public and ministry staff to locate licenced dairy plants.
