That's a great question.
The data that we use comes from police-reported information management systems. If I look at the trend data from 2011 to 2017, there were year-over-year increases in the number of police-reported incidents. In 2018-9, there were really high numbers, and in 2020-21, it kind of flatlined.
To get the narrative, the story, the experiences from survivors would have been a qualitative study. There is some very good qualitative research in which there were one-on-one interviews with survivors of human trafficking. From a statistical perspective, though, what we always have to grapple with, and what we are asked often, is the overall prevalence. How big is that problem?
When we have victims who are scared for their lives, who are concerned about their families, their friends, and scared about being abused if they go to the police, capturing the data from the police will always be just the tip of the iceberg. Any agency or victim service that is capturing information could help us understand the bigger picture.
However, as Ms. Walker said, funding for victim services is all over the map. Do they have the resources and the staffing to collect information? Then, from a comparability perspective, with so many frontline services available, how do you harvest all of that information to give us the big picture?
From Statistics Canada's perspective, we rely on the police-reported data. We get data from some shelters. We're working now with the Canadian hotline to look at their data so we can make a nicer picture to explain what we think is going on.
