The earliest data we have is from 1997, again through Statistics Canada. Comparing data with that specific year, there has been a rise. The biggest rise in temporary work was around that time. In earlier studies, they calculated some numbers in the past of just overall precarious work. Before 1997 the rate was low, but with changes in the economy, as I mentioned, because of globalization and changes in workers' preferences, it shifted toward temporary work over time.
