Positive noises about the stop-gap plan to produce an oiler.
New Zealand is getting a brand new ice hardened tanker for around $500 million. Australia is getting a couple of Cantabria tankers for around $600 million a piece. The tide class is costing the British around a billion for 4 ships.
Had Canada bit the bullet early on it could have already built a couple of new tankers in Korea or Spain and saved themselves an absolute fortune.
