The media magnate tore a strip off a reporter in public on Wednesday after he had tracked him down on his cellphone.
The would-be candidate for the Parti Quebecois leadership said Montreal La Presse journalist Denis Lessard was out of order when he called him on his mobile.
The controlling shareholder of Quebecor Inc. said Lessard has been around for about 30 years and should know that press attaches are the correct channel to go through if they want to contact him.
"Where is it going to stop?" Peladeau asked reporters in a scrum in the hallways of the national assembly. "Is it going to go as far as the toilets?"
If reporters end up calling politicians on their cellphones, it will become a "free-for-all," he warned.
Peladeau also blasted journalists for trying to speak to him in stairways at the national assembly.
"What I've heard is that the stairwells are private."
The PQ member of the legislature said last month he doesn't have to answer reporters' questions, indicating he prefers Facebook as a means of communication.
Peladeau has become a Facebook aficionado in recent months and uses it regularly to criticize his political rivals.
