Can civilians sue police for wrongful arrest?

My 17 yr. old son was wrongfully arrested. My son had many alibis, both adult and teenage friends, none of whom had ever been charged with anything . The courts found my son totally innocent and exonerated him. They also charged the person with making a false statement to the police. The police had not questioned the alibis or investigated properly. They just went ahead and charged him. It was later proven the whole thing was fabricated. What recourse do I have as far as a lawsuit against police incompetence? Oh by the way, the accuser is a known drug dealer with a lengthly criminal record. The police should have known better and investigated more thoroughly! We live in Canada
