Talks are accelerating - and work is expected to continue through the weekend - as both sides are racing to clinch a deal next month.
"To sum it up: Anyone who thought that an end of the Brexit drama is in sight will have to think again", said analyst Thu Lan Nguyen.
Asked if an exit from Brexit was still possible, Mr Juncker said: "That is in the discretion of the British Parliament and the Government".
Britain could not only have a free trade accord like that with Canada but also extremely close relations in security, foreign policy and other areas, Tusk said after meeting Irish Prime Minister Leo Varadkar.
