My division is responsible for the General Social Survey. One of the cycles that are part of that program is called a time-use survey. We're asking a representative sample of Canadians to fill out a 24-hour diary in which they note all the time they spend on all the activities they do. That's a key source of information to capture unpaid work.
The last time we did it was in 2010. We're going to redo it in 2015.
With respect to your question, the average amount of time that women spend daily on housework was four hours and 15 minutes in 2010, compared to three hours and 42 minutes for men.
So we do have detailed information on how much time is spent on housework and other unpaid work.
