There has been at least one report of a door to door canvasser seeking donations for ReForest London. This scam also has claimed to be raising funds for EnviroWestern.
If you have recently been visited, and the fraudulent canvassers are still in the area, call 9-1-1 immediately, inform them that you have been defrauded, and request that they send someone to look for the people going door-to-door. If they are no longer in the area, you may contact London Police at their non-emergency line, 519-661-5670, and push '3' to file a fraud report. Please also contact ReForest London at 519-936-9548
