While the racial makeup inside the corrections system is changing, prison hiring practices have not kept pace, correctional investigator Howard Sapers said as he released his office's latest annual report to Parliament.
Sapers said close to a quarter of all inmates are aboriginal even though they make up only four per cent of the general population.
"Recent inmate population growth is almost exclusively driven by an increasing number of aboriginal and visible minority groups behind bars," he said.
"Today, four in 10 of the federal inmate population is comprised of non-Caucasian offenders."
As well, he says, black inmates are over-represented, particularly in maximum-security institutions.
Black offenders also report facing discrimination by being marginalized or even shunned from within the corrections system, he said.
He outlined an example of a cultural clash involving a prison literacy group where the majority of the participants were black.
The book up for discussion was Mark Twain's The Adventures of Huckleberry Finn.
"While this novel is considered a classic, it is riddled with racist terminology," the report said. "Black inmates were made to read racist words aloud that they described as 'degrading' and 'demeaning.'"
The novel was replaced only after some prisoners protested and refused to take part in the group.
Sapers called on the federal government to develop a national diversity-awareness training plan and hire new staff responsible for building networks between the prisons and outside cultural groups.
But his report appeared headed to a dusty shelf after Public Safety Minister Steven Blaney abruptly dismissed the recommendations.
"The only minority I would say we are interested in are the criminals," Blaney said.
"Correctional services has launched many initiatives throughout the years to reach out to communities and I believe that we are taking care of all inmates in a fair and proper manner."
One recommendation in Sapers' report — that Corrections Canada conduct an internal audit of how it uses personal information — was lauded by privacy commissioner Jennifer Stoddart.
"We are very pleased that the Correctional Investigator has called for an internal audit," she said in a statement.
"Year after year, our own office has identified serious privacy concerns with respect to Correctional Service Canada."
Prison inmates consistently file the biggest number of complaints received by the privacy commissioner's office.
The agency has investigated more than 11,000 complaints against Corrections Canada since 1983.
"We have seen too many cases of preventable and unacceptable privacy violations," said Stoddart.
