Second Canadian scientist alleges brain illness investigation was shut down

Exclusive: Prof Samuel Weiss said in leaked email that government halted efforts to tackle mystery illness

A senior Canadian federal scientist has alleged that the government shut down an investigation into a mystery brain illness in New Brunswick that he believes may have affected 350 people.

He is the second federal scientist to accuse the government of deliberately halting the investigation and to say that the caseload is higher than the government has acknowledged.
