This "levy" is attempted every other year or so. I do not believe it has ever passed on any generic digital consumer media. Usually it is very far reaching. The last time I saw it proposed it woul dhave increased the storage cost of removable media as well as fixed disks by a significant percentage. The time before that retailers tried to take advantage of the supposed "new law" and started hiking CDR prices. That law never came to pass and the prices soon went down again.
There is likely a tax imposed on MUSIC CD recordable media (media that works in audio-based commercial or consumer recording devices), but there isn't on run of the mill media. You can buy CDRs for 30-something cents Canadian each in spindles (or less) right now. At least in the Toronto area. That doesn't leave any room for a media tax on the order of tens of cents per disc. I'm pretty sure a similar tax did exist on audio cassettes. Not that it's very relevant now.
The majority of removable media is never used for music, so any such tax would be highly unethical. The only way for something like this to pass is through the shadows. Easy to kill if it's publicized enough. And if it made it into the Star, it'll likely be shot down. Again.
