Narrative:

Shortly after lifting off of runway 30 at yeg, the terminal controller (departure) advised us that we had traffic at 1 O'clock at 4500 ft MSL. My TCASII, about the same time, issued a TA and showed the aircraft at 1 O'clock and about 3 mi, 800 ft above us. Other than the initial advisory the controller did nothing in the way of headings to keep us separated from the other traffic. My TCASII next issued an RA, which we followed. I believe that we passed at the same altitude and less than a mi horizontally. Luckily my first officer spotted the traffic visually and we were able to stay clear of the traffic. I shudder to think what might have happened had we not had TCASII and my first officer's sharp eyes. The controller was absolutely useless and, I felt, rather unimpressed or not motivated to keep us separated or provide advisories. After steering clear of the traffic terminal control issued headings for on course and the rest of the flight was uneventful.

Title: TCASII AIDS IN TFC AVOIDANCE.

Narrative: SHORTLY AFTER LIFTING OFF OF RWY 30 AT YEG, THE TERMINAL CTLR (DEP) ADVISED US THAT WE HAD TFC AT 1 O'CLOCK AT 4500 FT MSL. MY TCASII, ABOUT THE SAME TIME, ISSUED A TA AND SHOWED THE ACFT AT 1 O'CLOCK AND ABOUT 3 MI, 800 FT ABOVE US. OTHER THAN THE INITIAL ADVISORY THE CTLR DID NOTHING IN THE WAY OF HDGS TO KEEP US SEPARATED FROM THE OTHER TFC. MY TCASII NEXT ISSUED AN RA, WHICH WE FOLLOWED. I BELIEVE THAT WE PASSED AT THE SAME ALT AND LESS THAN A MI HORIZONTALLY. LUCKILY MY FO SPOTTED THE TFC VISUALLY AND WE WERE ABLE TO STAY CLR OF THE TFC. I SHUDDER TO THINK WHAT MIGHT HAVE HAPPENED HAD WE NOT HAD TCASII AND MY FO'S SHARP EYES. THE CTLR WAS ABSOLUTELY USELESS AND, I FELT, RATHER UNIMPRESSED OR NOT MOTIVATED TO KEEP US SEPARATED OR PROVIDE ADVISORIES. AFTER STEERING CLR OF THE TFC TERMINAL CTL ISSUED HDGS FOR ON COURSE AND THE REST OF THE FLT WAS UNEVENTFUL.
