The Trump administration in February temporarily ordered NOAA to stop communicating with foreign nationals, which included Canadians and included sharing data.
I don't know if that is still in effect. Google "Did the US stop sharing weather data with Canada?" or ask your favorite LLM that provides references for its answers for more information.
Google says: no, the US did not stop sharing weather data. Communication isn’t automated weather data sharing. The data never stopped. Again, citation needed.
Meanwhile, NOAA and EUMETSAT are preparing to launch a joint satellite later this year.
