Notices:
As of Dec. 15, the OTTAWA MACDONALD-CARTIER INT’L A and HAMILTON A airport stations will switch over to new partner maintained and operated stations. Due to a new format, hourly data from these stations will not be available on our website. We ask for your patience while we are working to upgrade our system to display these data. If you are interested in daily data for these stations, they can now be found under their new partnered station names, OTTAWA INT’L and HAMILTON. If you have any questions or concerns, please contact us at climate.services@ec.gc.ca.
We are currently experiencing some problems with the French version of the Climate Summaries on our Products & Services page. We are working to rectify the problem and ask for your patience during this time of technical difficulty. In the meantime, please refer to the data available from the English Climate Summaries page.
The Notice Inventory contains a record of all past and current Notices.
