No. Northland still uses Central Station, though it remains the only tenant. The commuter buses to surrounding towns in Ontario and Quebec use Albert and Slater, even after the LRT opened.
If it were me, I'd move whatever is left of intercity bus services to the VIA station, which has a bus lane under the canopy and plenty of room, and better transit than Central Station, which was not well-served at all, despite its "Central" location. I remember arriving there from Pembroke in 2019 on a rainy night, and deciding to walk to my hotel downtown because it was faster than waiting for a bus. It would allow for connections from the upper Ottawa Valley and Northern Ontario to and from Montreal and Toronto, should Greyhound disappear for good.
