In August, the company announced it was initiating a quarterly dividend of C1.5c per share.
"We continue to see significant potential upside in the re-rating of our share price. In addition to the recently announced quarterly dividend, the NCIB is an important component of our value creation strategy as the repurchase of shares using our free cash flow provides a permanent favourable impact to our earnings and cash flow per share metrics," said executive chair Serafino Iacono.
