The Canadian Commission for Radio and Television (CRTC) has ordered Quebec to comply with its regulations.
CRTC called the TVA Group at a public hearing Wednesday to explain its decision to suspend TVA Sports's signal to Bell's subscribers at the beginning of the NHL play last week.
The broadcasting regulator found that TVA Group violated CRTC discretionary regulations by denying the signal.
If the TVA Group fails to comply, it may face a fine of up to USD 250,000 for the first violation and USD 500,000 for each subsequent violation.
If you reset or disturb the TVA Sports signal before resolving a dispute with Bell, TVA Sports will automatically suspend your license for the duration of the Bell Canada no signal.
CRTC has created a rule protecting Canadians from losing access to television services during commercial negotiations between broadcasters and television service providers.
"CRTC is very concerned about the TVA Group's activities," Ian Scott, CRTC president, said in a statement.
"Not only are their actions seriously violating our regulations, but hundreds of thousands of Canadians are deprived of the channels they subscribe to."
"Having a license is a privilege, not right," Scott said.
TVA Group claims Bell does not pay a fair price for its services. At a hearing Wednesday, Quebec owner Pierre Karl Péladeau pleaded for fair rates, saying it was the fate of TVA Sport.
