Ottawa-based Mitel announced Monday it will be added to the S&P/TSX Canadian Indices, effective after market close on Friday.
“Being included in the S&P/TSX Composite Index in Canada, where we are headquartered, acknowledges Mitel as one of the country’s premier technology investments,” CEO Rich McBee said in a statement, “and increases our exposure to a broader range of institutional and individual investors who will benefit from the enhanced liquidity we expect to see for our securities.”

Mr. McBee said the whole Mitel team has been “working hard to deliver ongoing shareholder value and profitably grow our business.”
