Chan dominated the fifth ISU Grand Prix of Figure Skating event of the year smashing his combined total world mark of 280.98 in the men's event out of the water by scoring 295.27 in Paris.
That came after Chan bettered his free skate world record score to 196.75 following on from a new mark of 98.52 in the short program the day before.
His performances are a fine marker ahead of the Olympic Games in Sochi in February with Canadian teammates Tessa Virtue and Scott Moir also victorious in the ice dance in France.
And there was so nearly three Canadian wins but Qing Pang and Jian Tong of China beat Meagan Duhamel and Eric Radford by just 3.03 points in the pairs.
And Chan, who has won the last three World Championship men's titles after silvers in 2010 and 2009, admitted he will be logging his outing in a safe place ready to use again this season.
"This is a special day," said Chan. "It's the first time in a long time I've skated two strong programs at one competition. I felt in control of every moment and each element.
"I'm going to remember how I approached both programs. I know exactly why the way I skated. I paced myself properly to get through the whole program and through all the elements. That's where I improved."
Meanwhile in the ladies, American Ashley Wagner held onto for victory despite being beaten by Adelina Sotnikova in the free skate, her overall score of 194.37 just better than the Russian's.
