We have grown single crystals of electron doping system Ca_<2-x>La_xRuO_4 (0.00 ≤ x ≤ 0.20) by a floating zone method. The first order metal.1/non-metal transition and canted antiferromagnetic ordering occur for 0.00 < x < 0.15, similar to those in the bandwidth controlled system Ca_<2-x>Sr_xRuO_4 (CSRO). However, comparing with CSRO, we found a rather different metallic ground state adjacent to the non-metallic ground state with canted antiferromagnetic order. In-stead of short-range antiferromagnetic correlation found in CSRO (0.20 ≤x ≤ 0.50) , the metallic ground state of the present system is characterized by strong ferromagnetic correlation.
