In Canada, once you have paid for a license of a movie, it is legal to rip it from a physical copy, or download a digital copy.
In Canada when you play money, you have to get something in return in the form of a physical item, a license, a limited license, or a service.
Home videos were going to be under the physical item category originally. The problem the MPAC had with this is that legally, in Canada, you cannot put any restrictions on what people do with an item that is labeled as physical.
The MPAC wanted home videos only to be used for private showings, thus they lobbied to have home videos be classified as a license. The problem they have now is that you own a license to watch that performance of the movie. If you have a VHS copy of The Jungle Book, it is legal for you to download the 1080p version and watch it.
The movie studios, or record companies, can get around this a bit by coming out with modified versions of the movies, or music. There is a threshold for how much change there needs to be for this to happen.
Also Herr Harper passed a law making it illegal to teach other people how to crack encryption. Though cracking the encryption for personal use is not illegal.
Basically, if you buy a movie, you own a license to view that performance, doesn't matter how you get it. Higher quality transfers, or remastering are generally still considered the same performance.
