I believe 289-444-5482 is the contact # for a fake package delivery service: SCW Ground -delivering P&G Pkg.
A middle aged man came to the door July 28th... suspect car was silver with Ontario plates ZYAZ 1__?

I had the same delivery notice dropped in my mail box. called the number and got a cell phone  answering machine with some guys poorly recorded voice saying "you have reached SCW" , just another scam!
My advice .... throw the piece of paper out and go on with your life knowing you have just avoided another scam.
And yes.  your welcome :)
