The University of British Columbia’s probe into a pro-rape chant on campus has uncovered allegations of a second student chant referencing aboriginals.

The new chant was spotted by computer science graduate Benjamin Israel, who said he was surprised to pass a group of Sauder School of Business undergraduates singing in a group called “Pocahantas.”

“They all got in a circle and were banging on the ground saying, ‘White man steal our land, white man steal our land.’” Israel told CTV News, adding that the students were not aboriginal.

“I looked at the other fellows on the benches and we were all surprised.”

Israel said it didn't seem like the group was trying to be offensive, but that the chant was clearly rehearsed.

Student leaders said the theme of the frosh week, organized by the Commerce Undergraduate Society, was Disney films, and groups were named after different movies.

A UBC First Nations professor sympathized with students who believed they were merely referencing a cartoon – but said imitating native people on what is considered by the Musqueam to be their territorial land is insensitive at best.

“I’d say it’s not up to them to decide whether it’s racist. What their intent was is not the same as its impact,” said Daniel Justice.

University administrators promised to investigate the chant at a press conference Wednesday morning, where punishments were announced for 81 frosh leaders in connection with the earlier chant promoting sexualized violence.

UBC vice-president Louise Cowin said the university’s investigation into the chant revealed it had been an "oral tradition" for a long time.

“No one intervened to stop this chant and the vast majority of first-year students would have been exposed to this chant,” she said.

No student leaders ordered the chant to be said, she added. Four student leaders have already resigned in response to outcry over the incident, and the university has now decided to make 81 frosh leaders do community service.

The Commerce Undergraduate Society will also apologize and donate $250,000 for counseling.

“I’m extremely sorry,” said UBC President Stephen Toope. “I am determined that our welcome weeks will make students feel accepted.

“But I am not sorry that this has come to light. We have been given an opportunity to seize this moment and strike at the casual indifference to sexual violence and intolerance that still marks pockets of our society,” he said.
