Look:

-The Globe & Mail is owned by Woodbridge, holding company of the multi-billionaire Thomson family. 

-Postmedia is predominantly owned by Greentree Capital, a rich investment house in New York City.

-Quebecor is owned by the Peladeau family, whose stock there alone is worth nearly $1B.

-CTV is owned by BCE which has annual profits of over $2B, and whose four largest owners are Canadian banks.

-Torstar is has a convoluted ownership structure more devious than anything even Conrad Black thought up, but it is ultimately controlled by a group of very rich Toronto families.

-Global is owned by Corus which is majority owned by Alberta billionaire JR Shaw, a major rent-taker from the original CRTC cable TV land rush.

These are rich, sophisticated interests.  If their investments in Canadian media are not working for them, their recourse is to sell them for value in the capital markets, NOT to suck the blood of everyday Canadians.  If Trudeau gives them money he's a thief.
