The key principles of the Montreal Declaration include:
* Equity: Access to organ transplantation should be based on medical need and not on financial or other social factors.
* Justice: Organs should be allocated fairly and equitably, taking into account both the needs of the recipient and the potential harms to the donor.
* Transparency: The organ transplantation process should be transparent and accountable to the public.
* Respect for human rights: The rights and dignity of both organ donors and recipients should be respected.
The Montreal Declaration has been widely endorsed by medical and transplant organizations around the world, and it has helped to shape policies and practices in the field of organ transplantation.
