Check out this blog post, especially the comments. It reports that the Canadian government is actively seeking information about the use of “No-Charge Licensed Software (typically referred to as Free and Open Source Software or FOSS and also applicable to freeware).”
It was not too long ago that I had to write to the webmaster of the Canada Revenue Agency to see if they’d consider including Firefox as one of their approved web browsers. I didn’t receive a response, but others must have also written in, as it is now one of the choices.
One can hope.
