I would say that the schedule, as it now stands, covers the waterfront. If you were to expect a strategy to address all of this, you would be looking for a plan that was simply too huge and too complicated to be manageable, implementable, developable, measurable.
In the text of the bill, I'm not sure you need a schedule. You could say that you want a strategy that addresses the major sustainable development challenges and objectives of the Government of Canada, something like that. You could give broad direction to what you're looking for, and then see what they come back with. If you don't think the government is really addressing a big issue, say, GHG emissions or water pollution, then you could hammer them. But I wouldn't try to spell that out in detail in the bill.
