Europe's first geostationary sounder satellite is launched

Do you have more context? Naively, one would assume the geostationary satellites the US already has in orbit can see Canada just fine.

access is however, gated behind the american government, and relying on american satelites is a national security risk to canada.

for example, the US has stopped sharing weather data with canada.

Citation needed. Most weather data from NWS is required by treaty to be disseminated through WMO compliant methods. The Metsat data is transmitted unencrypted from the GOES sats. I don’t believe they even have the capability to encrypt it. It’s only DoD weather data that’s not being widely disseminated, AFAIK.

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.
