I don't know if our intention in the future is to track that information per se. WiC is not only about the job posting, but also additional information that is provided by the local labour market. Basically, the main source of data to determine what are the wage rates that people can expect for different types of jobs mostly comes from the labour force survey. Basically, when Statistics Canada is collecting information on the number of people who work in the labour force, they also ask them what is the wage rate, which is the main source of data that is used for that.
