Very quickly, I'm not aware of a single ILO definition of precarious employment. I do know that they think in terms of the transfer of risks and responsibilities from employers to individuals that I touched on.
I think that the key components have to be a subjective and an objective component to understanding labour market insecurity in all of its dimensions. There's no simple, ready-made, universal, international definition that we can simply sign on to.
There is good reason to explore a measure that is adequate to the Canadian context, keeping in mind what other countries have done to try to get a handle on this phenomenon.
