We got a call from this man, also claiming to be putting CPR classes together. Then a few days later, a woman appeared at our door to follow up. We had NOT given him/her our address. Told woman to come back another time (not at dinner hour). She was driving an Acura, ONT licence BCRV 631. Then tonight, a man came to the door, wanting to collect $30 registration fee for the CPR course. He refused to provide any written information, saying that all the info would be in the registration package that arrives later (after they've been paid). The supposed CPR classes were going to be held in 'various places nearby', churches, schools, etc.
Sounds suspicious to me.
