The owner of Toronto Trump Tower (which is not owned by Trump, but by Russian oligarchs) has defaulted on its loan and is seeking a court-supervised sales process.
Also, earlier this month at least one unit buyer was let out of his contract because of misleading marketing. Many more are asking for the same.
The Trump Organization is paid to manage the building and license the Trump name. I think it is likely this contract will be terminated as a way to maximize the value of the building.
A detailed article from April 2016 telling the unfortunate story of the tower can be found here.
