Jody Carr says a district superintendent made the decision to cancel a class trip in February to a rally in Fredericton for Liberal leadership candidate Justin Trudeau.
Carr confirms that he sent an email to his department's deputy ministers reminding them of the policy before the Trudeau event, but he insists it was the superintendent who made the final decision to cancel the trip.
The minister says the policy states that the department should not be paying for students to go to partisan events.
Carr, a Conservative, says the decision had nothing to do with the fact that it was a Liberal rally.
He says the government welcomes party leaders to visit schools and speak to students about politics.
