Is there any information on these 'AVR cards'? and/or the tests Industry 
Canada did.

I've used used Atmel AVR chips in embedded designs in the past. If I had 
some specific chip numbers or schematics, I couldn't tell you for sure 
whether they would cause interference, but I could give you a good idea 
of the likelihood of such interference.

Has Industry Canada not published their test results? If not, why should 
anybody take them seriously?

I think it is quite likely that, aside from the inappropriateness of 
using radio interference to justify the regulation of the gray market, 
you can prove that their assertions about such interference are quite 
simply wrong.
