Dalhousie University issued a statement Saturday to say it "completed a full investigation" after it was notified on Nov. 1, 2014, of concerns over an Instagram account.
The statement says the account contained "possible inappropriate content" but does not give further details.
"We can confirm that a number of students were evicted from residence as a result of this incident," the statement from the Halifax University said.
The Halifax Chronicle Herald reported on Friday that a female student at Dalhousie said she saw a photo posted last October on an Instagram account called "The Dal Jungle" that showed another female student with her breasts visible, engaging in oral sex.
The student told the newspaper the account also contained other nude photos of students at her school.
Dalhousie wouldn't confirm the newspaper account, but the statement said "the university took immediate and appropriate action."
The school says it brought the incident to Halifax Regional Police on Nov. 13 and police concluded there were no grounds for investigation.
Dalhousie says it also contacted Instagram and had the account taken down.
"We recognize that this type of incident is not isolated to Dalhousie University," the school said.
"It is part of complex societal issues in which we have fully engaged."
In a separate incident, Dalhousie suspended 13 male dentistry students from clinical activities in January for allegedly participating in a Facebook group that contained sexually violent content about female classmates.
