In 2021, the City worked with J.L. Richards and Associates to perform a preliminary study of the open-loop geothermal resource potential within Ottawa. It is important to note that this study only looked at open-loop geothermal resource potential. Most areas in Ottawa have a strong closed-loop geothermal resource potential.The interactive map shows the open-loop geothermal resource potential within Ottawa. More detail can be found in the Open Loop Geothermal Resource Scoping Study.

Accuracy: Data is accurate and it is simply the coordinates of each one of our locations that can be plotted on a geoOttawa map.Update Frequency: Will review on a yearly basis however, it can vary depending of if new branches are added or removed.Attributes:Geographical coordinates.Contact: Cole Duthie

Long-term freshwater quality monitoring data for over eight sites in the Ottawa River basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) as well as through the Canada-Quebec Water Quality Monitoring Agreement and the St. Lawrence Action Plan to assess water quality status and long-term trends, detect emerging issues, establish water quality guidelines and track the effectiveness of remedial measures and regulatory decisions. Data for sites operated by the province are available from Quebec's Sustainable Development, Environment and the Fight against Climate Change Ministry. http://www.ec.gc.ca/eaudouce-freshwater/default.asp?lang=En&n=50947E1B-1

Contained within the Historical Maps, 1639 to 1949, Atlas of Canada map series, is a reproduction of one of the bird's eye view sketches of cities which were very popular in the late 19th century. In this case, it is a black-and-white sketch drawn by Herm. Brosius and originally published by Chicago Litho. Co. As of 1876, Ottawa consisted of only part of Centretown, Byward, and Sandy Hill. The view lists dozens of major buildings at the time. It also has a sketch of the three buildings of Parliament. Of interest, all streets and railway lines are named.

City staff and community partners work together to survey people experiencing homelessness in Ottawa. So far, the City has led two counts:April 2018October 2021Oct 2024The survey is conducted to gather information about people experiencing homelessness. The goal of this work is to guide new approaches to address homelessness at a local level and help in the planning and delivery of services.Date created: 28 April 2022Update frequency: As needed.Accuracy: Convenience sampling was used to recruit survey respondents. This method of recruiting respondents to answer the survey does not rely on a random selection process. Instead, surveyors approach potential respondents if they are close by at the time the surveyor is delivering the questionnaire. Many factors could determine participation in the survey including:Number of community partners involved in the PiT countLocation of surveyors and their physical proximity to potential respondentsNumber of engagement eventsSeason the survey was conductedDifferences in results between PiT count years may be due to changes within the homeless population and shifts in methodology. For comparisons of emergency shelter use over time, visit the Temporary Emergency Accommodations Dashboard.

Neighbourhood refers to an inhabited area delineated by social and physical boundaries. ONS neighbourhood boundaries were derived based on census tracts, physical and demographic similarities, physical barriers (e.g. waterways, highways, etc.), maps used by the real estate profession (e.g. the Ottawa Multiple Listing Service), consultations with community stakeholders, as well as fieldwork by ONS researchers.Accuracy: Boundaries are generalized (non-densified). Neighbourhoods are subject to a minimum population in order for data to be reliable at a neighbourhood level (i.e., not all individual communities can be separately represented within neighbourhoods).Small communities cannot be described separately by the ONS because the population size is too small to create reliable estimates for many measures. Unfortunately, when small communities are included in larger neighbourhoods their unique character may be lost. This is a shortcoming of studies of this kind. Those who are using the ONS to help inform their planning decisions need to understand that the neighbourhoods described here may hide the unique strengths and challenges of some distinct communities or neighbourhoods within them. The ONS should be regarded as only one source of information; other sources that help identify these variations also need to be considered as part of any decision making process.Update Frequency: As needed (official review every 5 years)Contact: Ottawa Neighbourhood Study (ONS)
