Constellation Software Inc. might have a new leader, but he's sticking with an old strategy. Less than a week after being named president, Mark Miller said Wednesday that he's keen to keep the Toronto tech firm on the path his predecessor laid out. "We'll just continue to focus on the same things that we always have here at Constellation," Miller replied. Miller sold a company he co-founded to one of those subsidiaries, Volaris Group, in 1995, the same year Constellation was founded. "We've never been a fan of doing buybacks at Constellation," Miller said.
