Ontario's Healthy Babies Healthy Children program helps infants and children up to age 6 and their families through: * risk screening and assessments * referrals to community programs and services * supports for new parents These shapefiles provide geospatial data for mapping the 34 Healthy Babies and Healthy Children delivery regions in Ontario. __Please note:__ The Healthy Babies Healthy Children program is delivered through Ontario’s public health units in partnership with hospitals and other community partners. The Healthy Babies Healthy Children boundaries align with Public Health Unit boundaries.

This index identifies project areas on provincial highways where aerial photography and photogrammetric mapping has been collected.

The Ontario Railway Network (ORWN) is seven data classes that use the federal GEOBASE standard for the National Railway Network (NRWN) geospatial data. The seven data classes include: * track * crossing * junctions * marker posts * structure lines * structure points * stations Although the ORWN is mainly used as base data for cartographic products, users will also get railway-associated attributes.

This dataset contains Lake Ontario prey fish abundance and distribution statistics, collected every year during spring and fall bottom trawl surveys. The New York State Department of Environmental Conservation and the U.S. Geological Survey have conducted annual, spring and fall bottom trawl surveys in U.S. waters of Lake Ontario since 1978. In 2015, the Ministry of Natural Resources and Forestry started contributing to this program to include survey coverage in Ontario waters. The ministry also intermittently conducts mid-water trawling during the summer months on a limited geographic area largely confined to the Eastern Basin. The survey has varied sample distribution across lake depths and jurisdictions. The south shore of Lake Ontario has well-distributed coverage of depths between 8 and 200 metres. Coverage along the north shore is less uniform due to a lack of suitable trawl sites at shallower depths.

This date set contains up-to date information regarding current and future roadwork occuring on provicnally owned and maintained highways, and is available to be viewed on [Ontario 511](https://511on.ca) under the "construction and roadwork" layer. This data set can also be viewed on the Ontario 511 text report page at https://511on.ca/list/roadwork.

This dataset consists of information from reports received by the Spills Action Centre (SAC). They are generated and completed by SAC following the initial report of a spill. The data includes: * the reference number assigned to the spill * the municipality in which the spill occurred * what was impacted (e.g. land, water, air, or combination) * the substance being discharged (e.g. oil, gases, chemical, etc.) * whether the environmental impact is confirmed, possible, or not anticipated, and * the source/sector of the spill. The data reflects the information as reflected in the report, following the incident. All spills reported to SAC are recorded in the database, regardless of whether or not the Ministry provides field response.

The Ontario Watershed Information Tool (OWIT) is used to calculate information about Ontario’s watersheds. Watersheds are areas of land where surface water converges to a single point. Water professionals in the public and private sectors and academia use OWIT to better understand water flow in Ontario. The general public use OWIT for educational or general interest purposes. You can use the tool to: * create a map of a watershed * characterize the watershed * extract land cover information

Hamlets are smaller settlement areas identified in municipal official plans, generally without municipal water and sewer servicing. For precise boundaries and locations of hamlets, the appropriate municipality should be consulted.

This data provides core information on truck travel and commodity flows on the provincial highway network and other significant truck corridors. It provide ESAL information for all provincial highways and other significant truck corridors by road segment. *[ESAL]: Equivalent Single Axle Load
