Narrative:

We departed runway 33R on the toronto 3 departure. At 1100 ft MSL we turned to heading 320 degrees. Immediately after reaching the 320 degree heading, we experienced a TA alert followed immediately by an RA. The RA depictions and commands called for immediate evasive action. The RA depiction on the 5 mi range showed an immediate impact pending, with a countdown of 500 ft, 400 ft, and possibly 300 ft and 200 ft to nearest point of closure. There was no noticeable movement of target threat -- it appeared to stay dead center. As the captain watched the countdown the first officer's vsi depicted the green escape at the bottom of the vsi. We complied with the escape procedure and returned to yyz. Reported an RA to ATC at the same time. At the gate all passenger assured the crew and paramedics that they were physically ok, and that they were wearing their safety belts. After deplaning, we went into operations and called the chief pilot. As a crew we thought we were dead. Callback conversation with reporter revealed the following information: reporter stated that their evasive action was extremely aggressive with pitch down attitude and commented that everything went to the ceiling. Reporter believes the other aircraft was an air carrier but they did not visually see the aircraft as they were IMC. Reporter alleges the departure controller said there was no traffic in the area. Analyst learned that no follow-up action/call was made to the facility regarding the incident. Reporter stated that their aircraft was a carj.
