The trouble is, the results are not always easy to interpret. For instance, it is frequently said that feeding ATC to the internet is legal in Canada yet the radio regulator’s website seems to clearly state that reception of non broadcast traffic is prohibited.

The Cananian regulations are very similar to those of the UK and In the UK the equipment that is exempt would be declared in what is known as a statutory instrument. However, they and exactly what is defined within them are much more difficult to find.
In the UK it is almost impossible to find out what is legal and what is not until there has been a court ruling. The regulator makes the rules but does not give legal advice. It is up to the courts to decide what the rules the regulator has made actually mean.
