[6] Dimant retired from B'nai Brith Canada after a tenure of 36 years in September 2014 and was replaced by Michael Mostyn.
Dimant's announcement sparked a petition to the Nobel adjudication committee to protest the proposed nomination, stating it "would be a disgrace and insult to [the] prestigious award."
In the year following Dimant's retirement, B'nai Brith Canada put its "state of the art" care facility for Alzheimer's patients under insolvency protection while also trying to sell it.
The project, initiated and led by Dimant, was a $16 million facility opened in 2013 but that had been unable to attract enough patients, due to high fees for patients of $7,500 a month and the fact that it was not designed to be wheelchair accessible; the facility is losing $50,000 a month and owes $11 million to creditors.
[9] The Toronto Star article also claimed that other issues left by Dimant's former management of B'nai Brith were a lack of records, failure to always issue charitable tax receipts and poor corporate governance, with approximately 50 people who had believed they were on various boards of B'nai Brith organizations learning that this was not the case, as Dimant's management had failed to file the correct paperwork with government agencies.
