On uncosted liabilities

So even from the sketchy details made public so far, and even leaving aside the more general harm done by limiting government action and entrenching corporate monopolies, the Trans-Pacific Partnership will cost Canada:

• $4.3 billion in compensation to dairy, chicken and egg farmers
• Up to 20,000 lost jobs in the auto sector - meaning both lower revenues and higher costs for the affected communities [update: together with another $1 billion to paper over the damage]
• Job losses in other industries which are supposed to "adapt", again resulting in both higher costs and lower revenues
• A higher price for prescription drugs funded both publicly and privately

Naturally, none of those costs were taken into account in the budgets being relied on by any of Canada's political parties in developing their platforms. But now that we know they'll come with the TPP (while any supposed benefits tend to be longer-term to the extent they materialize at all), can we agree that any party open to ratifying the deal has to account for the price in its platform for the next four years?
