Federal cabinet minister Dominic LeBlanc said Monday that there must be a collective, global effort to fight the scourge of online disinformation.

Dominic LeBlanc easily won re-election in October in his New Brunswick riding of Beausejour, despite being unable to campaign while receiving treatment for non-Hodgkin lymphoma.

Nova Scotia MP Bernadette Jordan was named minister of fisheries, oceans and the Canadian Coast Guard.

In a statement, the New Brunswick MP and his wife thanked the doctors, nurses and staff at the Maisonneuve Rosemont Hospital in Montreal for the care he has received.

One political scientist expects Ginette Petipas Taylor and Dominic LeBlanc to have a key role and an important local voice with a minority government at the helm.

Dominic LeBlanc, a cabinet minister under Liberal Leader Justin Trudeau, is hospitalized for a bone-marrow transplant.

New Brunswick MP and federal cabinet minister was also questioned about free trip aboard J.D.Irving owned plane to Montreal for a medical appointment.

Trudeau's minister of intergovernmental and northern affairs is reportedly linked to five of the last six federally appointed judges in New Brunswick.

Duff Conacher of Democracy Watch says an investigation is necessary to determine if LeBlanc violated ethics laws by "participating in the decisions to appoint the judges."

The appointments include the wife of Dominic LeBlanc's brother-in-law and prominent donors to both the Liberal Party and the federal Liberal association for LeBlanc's riding.
