Former Telus top man Joe Natale officially took over as CEO of Rogers Communications Inc. this year, signaling a return to stable leadership for the company after former CEO Guy Laurence was axed last fall. The firm (which owns Canadian Business) has made a number of major moves leading up to and since then, including shutting down video service Shomi, paring down their print magazine portfolio and shaking up their management structure. So far, the changes seem to be serving the company well. In the latter months of 2017, the company’s stock climbed 7.8% as the industry stagnated at 0.8%.
