I think the sources of leak are plenty. Khalistani separatist movement of India (actually it is active only in Canada right no) is deeply embedded in Canadian politics and especially close to the current Canadian admin. (For example Trudeau once invited a convicted (by Canadian courts) terrorists and assassin from this movement of an official dinner). This classified information is likely available to Khalistani separatists working at different levels of Canadian government and they would have leaked it to foment more anti-India sentiments.
