Dear Mr. Trump,
It has come to my attention that you were in Vancouver this week to announce your new high-end hotel / condo tower in Coal Harbour, near where I work. My fellow citizens and I decided not to picket your event. Instead, I opt for polite correspondence, to respectfully inform you that we are sufficiently supplied with luxury condominiums at present and require no further units. We'll call if we're running low.
Plus, there is a lien on the place. Just ask the original inhabitants.
