File sharing in Canada is when people share digital files with each other, like music, movies, or pictures. It's like when you share your toys with your friends, but instead of toys, it's digital things.
However, some people share files that they're not supposed to, like movies or music that they didn't pay for. This is illegal and can get you in trouble.
To prevent this from happening, companies called copyright holders can try to stop people from sharing their files by sending warnings or taking legal action. This is to make sure that people get paid for their work and so that they can keep making more things for us to enjoy.
It's important to make sure you're only sharing files that are legal for you to share. There are some websites and programs that let you share files for free, but some of these files may be illegal to share. So it's always a good idea to check and make sure that you're not breaking any laws.
