Narrative:
After takeoff; in the climb: anti-ice duct warning message sounded. Leveled at 7000 ft to stay out of 10 degrees C temperatures which requires anti-ice for our CL65 aircraft. Took delayed vectors to return to field; and allow us time to run the associated QRH procedures and get set up for the approach. Temperatures decreased to 6 degrees C on descent to final approach course. No ice detection system alerts and no visual icing by flight crew. Denied ATC further vectors to final approach course to expedite our return to the field since we were now in icing conditions causing a B757 to be taken off final approach course to let us in. Performed an overweight landing at 48270 pounds to minimize our time in the icing conditions without anti-icing.

Title: CANADAIR REGIONAL JET RETURNS TO DEPARTURE AIRPORT AFTER RECEIVING AN ANTI-ICE DUCT WARNING MESSAGE SHORTLY AFTER TAKEOFF.
Narrative: AFTER TKOF; IN THE CLB: ANTI-ICE DUCT WARNING MESSAGE SOUNDED. LEVELED AT 7000 FT TO STAY OUT OF 10 DEGS C TEMPS WHICH REQUIRES ANTI-ICE FOR OUR CL65 ACFT. TOOK DELAYED VECTORS TO RETURN TO FIELD; AND ALLOW US TIME TO RUN THE ASSOCIATED QRH PROCS AND GET SET UP FOR THE APCH. TEMPS DECREASED TO 6 DEGS C ON DSCNT TO FINAL APCH COURSE. NO ICE DETECTION SYS ALERTS AND NO VISUAL ICING BY FLT CREW. DENIED ATC FURTHER VECTORS TO FINAL APCH COURSE TO EXPEDITE OUR RETURN TO THE FIELD SINCE WE WERE NOW IN ICING CONDITIONS CAUSING A B757 TO BE TAKEN OFF FINAL APCH COURSE TO LET US IN. PERFORMED AN OVERWT LNDG AT 48270 LBS TO MINIMIZE OUR TIME IN THE ICING CONDITIONS WITHOUT ANTI-ICING.
