"Fraudulently...without colour of right" means that you have NO legal right to it. The question was whether he could use the cable for the digital channels are discontinuing cable service. The answer is NO. That would be taking 'without color of right'. And *not* removing filters etc. has nothing to do with it.

As to whether you would get caught, that is a completely different question....But you are reading/posting here and it can be assumed that you are interested in the reception of digital television channels. You could email Rogers and ask. You might get an answer that amounts to 'we don't care. you have highspeed'. Then you could argue you have a colour of right because you relied upon the supplier (even if the 'help desk' was wrong.. (pity that that argument is not available when you are dealing with the government!)).
