Here is a picture of the chart: http://canadianspectrumpolicyresearch.org/wp-content/uploads...
And here is the original document from Industry Canada, in PDF but with a much higher resolution: https://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/2014_Canadia...
(This is the 2014 version so it might not be exactly accurate anymore, but I'm sure you can find more recent versions from Industry Canada)
Edit: here seems to be the latest (2018) version; a little bit less pretty at the top but still very cool: https://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/2018_Canadia... (via https://ised-isde.canada.ca/site/spectrum-management-telecom...)
Also, does anyone know why 275 GHz is the cutoff?
