Tuesday (jul 30) marks the International Day to End Trafficking in Persons.
An ad campaign, called ProjectONroute, had been running on screens in those service centres until today.
It has been replaced by #ProjectMapleLeaf which will continue raising awareness about the problem.
OPP Det Sgt Andy Taylor took to twitter to speak about what symptoms or signs a trafficked individual will exhibit.
If you suspect someone is the victim of human trafficking contact the Canadian Centre to End Human Trafficking or you local police.
