In most cases, the victims were outside their homes when they were approached by a group of people asking to be laid on the street on the same day, for cash and without a formal written agreement, police said. 
“The work being done is reportedly poor as the suspects are not removing the old asphalt or preparing the ground properly.  When the job is only partially done, they often leave saying they will return, but don’t finish the job or clean up large messes they left behind,” York Regional Police said in a July 26 news release.
“The suspects generally bid higher for the paving job than a professional paving company would.”
Researchers urge residents to trust their gut and use caution when considering unsolicited services.  They also encourage people to ask for references and do additional research to thoroughly verify that a company is legitimate and in good standing before accepting and paying for services.
Police believe there are more victims.
