I just came across an article stating that FCC just made 5.85 to 5.925 Ghz unlicensed for wifi use. It's not good news. I wonder if ISED (Canadian FCC) will follow.

Good point is that nothing is set yet and that RAC is aware of this and brought the issue in front of the IARU for further actions and will take actions at the ISED level also. But sadly if we do not get into that spectrum and show some use of it, we might well lose or at least take more noise.
