Thank you, that's what I needed to do! the specific question that was unanswered was:
"Do you authorize the CRA to share your name and email address with the Government of Ontario to contact you about organ and tissue donation, and to maintain the Organ and Tissue Donor Registry?
You are not consenting to organ or tissue donation. This authorization is only valid in the tax year you file this return."
Once I answered that, it let me proceed with NETFILE.
