The Ottawa-hosted ministerial meeting kicked off on Monday, with the two agencies being denied the accreditation. When asked by Sputnik to explain the decision, the ministry's spokesman Richard Walker said that it was made because the agency "hasn't been cordial" with Canadian Minister of Foreign Affairs Chrystia Freeland in the past.
On Sunday, Venezuela-based Telesur television network said it was similarly denied access to the Lima Group meeting by the Canadian government, which did not provide any reasoning behind the move.
The Lima Group comprises 14 member states, the majority of which have been critical of incumbent Venezuelan President Nicolas Maduro and have recognized opposition leader Juan Guaido as the country's interim leader.
Russia, China, Mexico and Turkey have stressed that Maduro is the legitimate president of Venezuela and called for dialogue.
