I would like to clarify something.
Let's say for example that I am a grandmother and I have created something. Seventy years is my grandchild's life expectancy. It is like saying that your house will only belong to you for two generations and, after that, anyone can live there. There is a limit.
From what we know, all countries are extending the duration of protection. The fact that the limit in Canada is 50 years leads to a loss of revenues. When Canadian works are disseminated in other countries that have 70 years of protection, the money collected by copyright collectives stays in those countries. It does not come back here because the law of the country of origin applies.
From our understanding, it is not commercially beneficial to refuse to extend this protection to 70 years.
