Wikipedia notes that cougars are reported to be in the eastern NA, with Quebec confirming:
"Currently, it ranges across most western American states, the Canadian provinces of Alberta and British Columbia, and the Canadian Yukon Territory. There have been widely debated reports of possible recolonization of eastern North America.[44] DNA evidence has suggested its presence in eastern North America,[45] while a consolidated map of cougar sightings shows numerous reports, from the mid-western Great Plains through to Eastern Canada.[46] The Quebec wildlife services (known locally as MRNF) also considers Cougar to be present in the province as a threatened species after multiple DNA tests confirmed cougar hair in Lynx mating sites."
