Unless the holder of the copyright has agreed to it, nothing published is "public domain".

Asserting copyright is the only way to protect copyright, if a copyright holder allows their work to be published without asserting their rights, they lose credibility and legal standing.

Last time I checked, the Toronto Globe and Mail is not a medical care provider, the idea that a newspaper even has a "duty of care" is simply absurd.

As for the being in the business stuff, time for a serious reality check.
