ClimateData.ca has undergone a major redesign to make it easier than ever to find, understand, and use high-quality climate data. Meet the Updated ClimateData.ca.

About Us

ClimateData.ca is undertaken with the support of Environment and Climate Change Canada (ECCC), the Computer Research Institute of Montreal (CRIM), Evolving Web, the Pacific Climate Impacts Consortium (PCIC), ClimateWest, the Prairie Climate Centre, ORCCA, Ouranos and CLIMAtlantic. Find out more about these organizations and our data using the menus on the lefthand side.

Canada’s climate is changing rapidly. Canada’s Changing Climate Report illustrates that Canada’s climate will continue to change due to global emissions of greenhouse gases (GHGs). Concerningly, this warming will lead to increases in extreme heat and extreme precipitation events, raise sea-levels, and cause further declines in snow and ice cover. All sectors of society and the economy are at risk from these climate changes. It is therefore vital for Canadians to incorporate climate change considerations in their decision-making processes.

Released in 2023, the National Adaptation Strategy provides a guiding framework for climate adaptation efforts across Canada. Online data portals play a key role in these efforts by providing access to the climate information needed to build resilience to climate change impacts across various sectors. Future climate projections and historical data, readily available via online data portals, help with the development of climate change adaptation plans, which can then make specific recommendations with more confidence. Even for experts, tasks like accessing large amounts of reliable data, conducting a thorough analysis and computing key variables for a specific region can take months and cost several thousands of dollars. To support and enable Canada’s climate change adaptation planning, and improve access to relevant climate data, we are proud to present ClimateData.ca.

ClimateData.ca offers a wide range of resources related to historical climate data, climate projections, and analysis tools. The platform includes datasets on temperature, precipitation, and other climatic variables, as well as interactive maps, graphs, and educational materials to support the assessment of climate change impacts and the development of mitigation and adaptation strategies.
