The Ontario Teachers’ Pension Plan purchased or increased its stake in a number of telecom companies last year, according to its 2007 annual report.

The plan bought 8 million more shares of BCE—which it plans to take private—to hold 50.8 million shares, valued at approximately $2.03 billion at the end of last year. Out of all the publicly traded companies Teachers’ owned at the end of 2007, BCE was the largest holding.

Teachers’ also invested in Deutsche Telekom, holding 46.6 million shares valued at $1.01 billion, making it the third-largest holding. The company was not one of its stock holdings of more than $100 million at the end of 2006.

The plan upped its stake in Manitoba Telecom, buying an additional 1.8 million shares to hold 5.7 million shares valued at $267.7 million.
