Telus, which has been attracting more postpaid wireless customers amid heightened competition, said it would invest more than $900 million this year alone in Alberta.
The company is in a heated battle with Shaw Communication, which has recently enhanced its high-speed internet and cable TV products.
The strong growth for both major Western Canadian companies comes as Alberta recovers from an economic slowdown caused by a prolonged slump in oil prices from late 2014 though early 2016.
Telus just recently announced it would invest $4.7 billion in British Columbia for similar infrastructure upgrades as those in Alberta.
