Elementary Teachers’ Federation of Ontario

The Toronto Sun reported that Fisman was retained by the Elementary Teachers’ Federation of Ontario to provide an opposing opinion on school reopenings in a document dated September 2020. Fisman served on the science table at the same time. It’s a situation that one leading expert says is a potential conflict of interest and Ontario Premier Doug Ford’s office calls “deeply concerning.”

“Where a person receives payment for speaking on behalf of a special interest group, it would almost certainly be appropriate to declare this as a potential conflict of interest when working in roles that are even slightly related,” explained Dr. Euzebiusz Jamrozik, from the bioethics research centre at Oxford University, in an email to the Sun.5)

This conflicted affiliation is further concerning because the Ontario Teachers’ Pension Plan (with which the ETFO is surely associated) is a member organization of the World Economic Forum,6) and holds financial stakes in several companies that benefit financially from the maintaining of online learning and mandatory masking and vaccination policies.7) Those companies include Mastercard, BlackRock, Blackstone, 3M (who manufactures masks), Abbott, Johnson & Johnson, and many others.8)

Fisman, D. (2021, August 23). It is with mixed emotions that I have decided to resign from Ontario’s science and modeling tables. I wish every success to the colleagues who remain on these tables. Ontario needs a public health system that is arm’s length from politics. [Tweet]. Twitter.
