New leader Tricia Smith had already promised that it will not be "business as usual" after she was elected to replace Marcel Aubut, who resigned in October in the midst of the controversy.

A review which followed was highly critical of certain practices at the COC, including the "lack of clarity" around the role and authority of the Board in comparison to that of the President.

Gaps in the areas of human resources systems and processes were among other flaws found.

Now, executive director of operations Judy Crute and chief of sport officer Caroline Assalian have been released, according to CBC News.

Assalian had been at the COC for more than 20 years and was responsible for the Olympics and Pan American Games.

Human resources manager Robert Cousin has also been let go. 

Aubut initially stepped down on a temporary basis in October after a woman who worked at the Canadian Olympic Foundation alleged harassment.

This complaint was withdrawn, but more alleged cases emerged and the 68-year-old resigned permanently.

Smith admitted that the finding of the review proved that the COC had "failed its employees".

"It is clear from the report summary that the Board and the senior leadership team could have done more,” she said.

“And for that, I apologise.

"We all own this and we are truly sorry."

Smith, a vice-president of the International Rowing Federation, won an Olympic silver medal in the coxless pairs alongside Elizabeth Craig at Los Angeles 1984. 

She was elected as COC President in November ahead of British Colombia-based lawyer Peter Lawless.

The 58-year-old promised one of her first tasks will be to introduce a senior-level and designated human resources manager, to create a "safe and healthy" work environment.

"We will be holding everyone's feet to the fire," she said.

"We will do that by ensuring everyone is 100 per cent committed to this new culture and accountable to the new policies and there will be ways to tell us if we are not meeting that standard."
