GFL Environmental Inc. is closing in on a deal to acquire Canada’s Secure Waste Infrastructure Corp. in a transaction valued at more than C$6 billion ($4.3 billion) including debt, according to a person familiar with the matter. The deal would rank among the largest waste sector acquisitions in recent North American history.

Secure Waste Infrastructure operates hazardous and industrial waste management services across Canada. A transaction of this scale would significantly expand GFL's presence in the specialty waste segment, adding considerable scale to its existing environmental services operations.

GFL, one of North America's largest waste management companies, has been actively pursuing acquisitions to fuel growth. The potential deal reflects ongoing consolidation in the environmental services industry as major players seek to expand their capabilities and geographic reach through strategic transactions.
