Companies in the news:

Rogers Communications Inc. (TSX:RCI.B). Up 88 cents or 1.4 per cent to $62.43. Rogers Communications Inc., Shaw Communications Inc. and the Competition Bureau have agreed to participate in a mediation process next month regarding the companies' $26-billion merger. The first scheduled mediation period is July 4 and 5, according to the Competition Tribunal. Public hearings before the tribunal were previously scheduled to begin this fall. The mediation announcement comes just one week after Rogers announced it would sell Shaw-owned Freedom Mobile to Montreal-based Quebecor Inc. for $2.85 billion in an attempt to ease the Competition Bureau's concerns about the combination of Rogers and Shaw. The competition watchdog has been trying to block the deal, arguing that it would ultimately result in less choice in the telecom market and lead to higher bills for consumers. Rogers, Shaw and Quebecor argue the Freedom deal would keep alive a "strong and sustainable" fourth wireless carrier in Canada.

Bausch Health Companies Inc. (TSX:BHC). Up $1.83 or 19.4 per cent to $11.28. Bausch Health Companies Inc. says hedge fund manager John Paulson has been named chairperson of its board of directors, replacing Joseph Papa. Paulson is president and portfolio manager of Paulson & Co. Inc., an investment management company, which he founded in 1994. He previously served on the board of Bausch Health from June 2017 to May 2022. The company says Papa's decision to resign from the board was not due to any dispute or disagreement with the company, its management or the board. Papa, who stepped down as chief executive of Bausch Health earlier this year, remains chairman and chief executive of Bausch + Lomb Corp., which recently completed its initial public offering and is being spun off from Bausch Health. Paulson is an independent director of Bausch + Lomb.
