"Is this really a priority for Canada or for Quebec?"
Yup, it certainly is a (real) Canadian issue. It will be lurking in our souls until it will be fully resolved (don't ask me how, cause I don't have an answer) ... does anyone remember those dark October days way back with the War Measures Act (whew, now that was a heavy scene in the Canadian psyche)... the kidnapping of James Cross, the murder of Pierre Laporte ... serious stuff in our history ... and as I said, the issue has never been resolved.
