This data layer comes from information recorded to the Operations Directorate of the Ministry of Public Security (MSP) during winter heat or spring flooding. The compilation was carried out using digital documents, papers, event reports or situation reports.The database also contains field observations made by municipal stakeholders grouped into river monitoring committees. These committees are set up and coordinated by the regional directorates of the MSP.Field observation is the collection of qualitative or quantitative data on the state of the river at a specific time. The level of the river can, when the situation applies, be measured using a limnimetric scale or evaluated using a geographic coordinate system as well as its trend (increasing, stable, or decreasing). General information characterizing the ice cover may also be recorded by the observer.The information in the database is consistent with the Canadian Common Alert Protocol Profile (PC-PAC). The PC-PAC is a set of rules and controlled values that support the translation and composition of a message to facilitate its sending by different means and from different sources.The PC-PAC formats used are as follows:SEVERITY LEVELThe severity level of the event based on the harm to life of persons or damage to property. The severity of observations on past events can therefore be estimated from the consequences recorded at the time of the events. For field observations by river committees, the degree of severity is generally estimated directly by the observer.The definitions are as follows:Extreme: Extraordinary threat to life or property.Significant: a significant threat to life or property.Moderate: possible threat to life or property.Minor: low threat to life or property.Normal: there is no threat to life or property.Unknown: severity unknown.EMERGENCYThe emergency level is determined based on the reactive measures that need to be taken in response to the current situation.The definitions are as follows:Immediate: reactive action must be taken immediately.Expected: Reactive action should be taken soon (within the next hour).Future: reactive action needs to be taken in the near future.Past: reactive action is no longer necessary.Unknown: emergency unknown.STATEThe state refers to the context of the observation, real or simulated.Current: information about a real event or situation.Purpose: To obtain an overall picture of the situation concerning ice jam flooding problems in order to estimate the risk of flooding along river sections subject to this problem.Geographically locate the ice jams listed on Quebec waterways.Characterize each case listed according to the severity level as defined in the PC-CAP common alert protocol.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Measurement of flow and level stations from partners of the Ministry of Public Security (MSP). The flows and levels make it possible to automatically monitor the risks of flooding in open water on rivers, watersheds and lakes where hydrometric stations are installed based on pre-established consequence thresholds. Other watercourses that do not have such instruments are also monitored by municipal and governmental authorities.Data from the following partners are integrated into the application and web services: Quebec Water Expertise Center, Quebec Water Expertise Center, Meteorological Service of Canada, Hydrographic Service of Canada, Hydro Meteo, Chaudière River Monitoring System, USGS...The latest level (m) and flow (m³/s) values are provided, when available, as well as the status of the station according to pre-established flood thresholds. The definition of states can be found here: https://vigilance.geo.msp.gouv.qc.ca/en-savoir-plus/stations#etat).This data is updated several times a day and is also visualized in the Vigilance - Flood Monitoring application.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

For the best experience, please follow the instructions available in the resources.**In replacement of the former Canadian Digital Elevation Model (CDEM) that is no longer supported, the Medium Resolution Digital Elevation Model (MRDEM) product is a multi-source product that integrates elevation data from the Copernicus DEM** acquired during the TanDEM-X Mission (AIRBUS, 2022), and the High Resolution Digital Elevation Model data derived from airborne lidar. This product provides a complete, 30 meters resolution, nationwide coverage for Canada. It includes a Digital Terrain Model (DTM), a Digital Surface Model (DSM) and other derived products. The spatial coverage extends into the USA, where needed, to provide coverage for cross-border watersheds in support of hydrological studies and applications. The MRDEM-30-DSM is partially based on the GLO-30 version of the Copernicus DEM** (hereafter named GLO-30). Since elevation values from the GLO-30 are referenced to the EGM2008 geoid model, they were transformed to the Canadian Height Reference System of 2013 (CGVD2013), using the CGG2013 geoid model. Where available, the MRDEM-30-DSM integrates surface data from the lidar-derived HRDEM mosaic, resampled from 1 m to 30 m. The process to generate the MRDEM-30-DTM is more complex. Where available, the HRDEM Mosaic derived from lidar was used since it already provides reliable terrain elevation values. The HRDEM Mosaic data used was resampled from 1m to 30m. Elsewhere, the processing workflow combines a forest removal model and a settlement removal model that is applied to the GLO-30 values in order to estimate the terrain elevation values. Both datasets are projected to Canada Atlas Lambert NAD83 (CSRS) (EPSG:3979).The MRDEM is referenced to the CGVD2013 which is the reference standard for orthometric heights across Canada.The product Medium Resolution Digital Elevation Model (MRDEM) is part of the CanElevation Series created in support to the National Elevation Data Strategy implemented by NRCan.** This product was in part produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014- 2018 provided under COPERNICUS by the European Union and ESA; all rights reserved.The organisations in charge of the Copernicus program by law or by delegation do not incur any liability for any use of the Copernicus WorldDEM-30.

Over the last year, Statistics Canada (StatCan) and Canada Mortgage and Housing Corporation (CMHC) have collaborated on the implementation of a set of proximity measures to services and amenities. CMHC funded this collaboration to generate data and analytical work in support of the National Housing Strategy.The result of this collaboration is the first nation-wide Proximity Measures Database (PMD). This database is now available as an early release to meet urgent information needs of departments and other stakeholders across Canada who are dealing with the COVID-19 crisis. The current situation involving COVID-19 emphasizes the importance of having timely and accessible information available to the public at all levels of government. Proximity measures developed for this project are relevant to the current situation by providing a wealth of information (at the granular level) in terms of proximity to health facilities, pharmacies and other essential services/amenities that can be used to make rapid informed decisions at different geographical levels.WARNING: This map contains detailed data which makes it heavy to load. To improve loading time, please uncheck the "Proximity measures" group from legend at loading, then load only the desired thematic.

The Ministry of Public Security (MSP) supports the development of knowledge of flood risks. In collaboration with Laval University and the Reunification of Quebec Basin Organizations, the MSP has developed a methodical and rigorous process for documenting floods that have an impact on the safety of people and essential goods.Thus, since 2017, the Ministry of Public Security (MSP) has been acquiring in certain cases data related to the water level reached when floods with proven consequences occur in southern Quebec. Maximum water levels are indicated by flood overflows.__What is a flood wasteland? __A flood (flood) is characterized by a rise in water on land that is usually dry, the reaching of a peak, then a descent of water (decline). Waste forms at the beginning of the flood when the water, when withdrawing, deposits materials that were in suspension or floating. These materials (mud, seeds, twigs and other debris) constitute flood wastes or flood plains.__Marking and surveying flood plains and water levels__The marking of floodplains and water levels takes place on the ground shortly after the peak of the flood. The physical indices of the maximum water level reached (abandoned by the flood) or of the current water levels are identified and marked using permanent markers (markers). Afterwards, a land surveyor will precisely record the location and the altitude of the markers. __Point dataset “Water levels during a flood"__The “Water levels during a flood” data set contains, for each marker, the date, altitude and location (measured by a land surveyor). There are two main types of observations made in the field: the natural flood defect (line of mud, seeds or trace of water) which indicates the maximum water level reached during the flood (called MAX) and the water level observed during the field visit (called CURRENT). The list of all attributes is provided in the dataset description sheet (Additional Information section).Despite the quality of the work carried out, the Ministry of Public Security cannot guarantee the absence of errors in the data.__Related datasets__ The “Flood markers” dataset produced by the Ministry of Public Security also contains maximum water levels reached during a flood. The link to this dataset is provided in the _Documentation_ section.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

>Warning: as of June 2020, this dataset is no longer updated and has been replaced. Please see https://www.donneesquebec.ca/recherche/fr/dataset/evenements-de-securite-civile for data on civil security events since June 2020. This database brings together in a structured way information related to past claims that have been systematically grouped and centralized by the Ministry of Public Security (MSP). The consequences and evolution of the events are documented and they have been categorized according to their level of impact on the safety of citizens, goods and services to the population based on criteria defined in the Canadian profile of the Common Alert Protocol. It is updated continuously by the MSP Operations Department (DO). This database will allow analyses to be carried out at regional and local levels and can be used by municipalities in the implementation of their emergency measures plans.The event history archives come from event reports and status reports that were produced by the Government Operations Center (COG) and by the regional directorates of the MSP. Among other things, we find: 1- Observations entered directly into the Geoportal by the civil security advisers of the regional directorates; 2- A compilation of information recorded in COG event reports and DO status reports distributed to MSP partners since 1996; 3- A compilation of the information contained in the files of the regional directorates. This can be information on paper, event reports or field visits, paper or digital maps, etc. The information in this database is consistent with the Canadian Common Alert Protocol Profile (PC-PAC). The PC-PAC is a set of rules and controlled values that support the translation and composition of a message to make it possible to send it by different means and from different sources. The severity level is an attribute defined in the PC-PAC. It is used to characterize the severity level of the event based on the harm to the lives of people or damage to property. This severity level is defined by the following characteristics: Extreme: an extraordinary threat to life or property; Significant: significant threat to life or property; Moderate: possible threat to life or property; Minor: a low or non-existent threat to life or property; Unknown: unknown severity, used for example during tests and exercises. The emergency level is determined based on the reactive measures that need to be taken in response to the current situation. It is defined by the following characteristics:Immediate: reactive action must be taken immediately;Expected: reactive action should be taken soon (within the next hour);Future: reactive action should be taken in the near future;Past: a reactive measure is no longer necessary;Unknown: Unknown emergency, to be used during tests and exercises.The state relates to the context of the event, real or simulated. It is defined by the following characteristics:Current: information on a real event or situation;Exercise: fictional or real information produced as part of a civil security exercise;Test: technical tests only; to be ignored by all. Confidence is defined by the following characteristics:Observed: would have happened or is currently taking place;Probable: probability of the event happening > 50%;Possible: probability of the event happening < 50%;Unlikely: probability of the event happening around 0%;Unknown: certainty unknown.When an event date was not known, the year 1900-01-01 was recorded.DESCRIPTION OF ATTRIBUTES:Observation date: date of the event or observation; Type: name of the hazard;Name: name of the municipality;Municipality code: municipal code;State and certainty: as these are real events, the state is generally “current” and the certainty is generally “observed”;Urgency: the term “past” has generally been used for events that occurred before compilation work was carried out;Imprecision: imprecision in data (the date of the event, its location, the source of the data or no inaccuracy noted).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
