I don't think that assertion is true, so I did some quick googling.
For example PostMedia received 35 million in government funds in 2021 according to pressprogress
Searching through Government of Canada Grants and Contributions you can find lots of public funds. here
My two cents, if it very important we as a society publicly fund Canadian news organizations to help keep them, fair, balanced and, trustworthy as it can be from both sides of the spectrum.
