Narrative:

It was the first leg of the night. We were delayed about 30 mins for loading. When given clearance; we were given runway 12 and planned on the hamilton 7 departure. While taxiing out; ground gave us a last min runway change to runway 30 with a new departure of glanbrook 1. We had just finished starting the outboard engines and were back-taxiing to runway 30 and were continuing our 'before takeoff checklist.' tower cleared us for takeoff and we continued with the checklist. My first officer said he was familiar with the airport and read off the departure instructions for the glanbrook 1. 1300 ft was set in the altitude select window. I repeated what the first officer briefed to be sure that I understood the new departure. We finished the proper checklists and took off. The first officer said to hold at 1300 ft and turn to 260 degrees. I did this; but we should have been climbing at the same time to 4000 ft. We got the 'don't sink' on the egpws. We caught the mistake and climbed to 4000 ft shortly thereafter. I should not have let myself get too rushed. I was at an unfamiliar airport and should have reviewed the new departure when given and not relied on my first officer. Supplemental information from acn 785921: the SID was briefed as calling for runway heading to 1300 ft and then turning to a heading of 260 degrees. Both pilots were in agreement of the briefed procedure. After takeoff; the SID and initial climb were flown as briefed. Shortly after leveling off at 1300 ft; departure control cleared us to climb to a higher altitude and a normal climb was initiated. During the climb the departure procedure was discussed among the crew since no one felt comfortable leveling off at 1300 ft. Upon further review of the SID procedure; it was discovered that 1300 ft was only the altitude to start the turn to 260 degrees. In another area of the departure chart was a box stating to maintain 4000 ft. Although there was no immediate danger from the brief leveloff at 1300 ft; if we would have had trouble contacting departure control; ground clearance could have become critical.

Title: AN ACR FLT CREW MISREAD THE DEP PROCEDURE ON TAKEOFF FROM CYHM AND LEVELED AT LOWER ALT THAN CHARTED; RECEIVING A 'DON'T SINK' WARNING.

Narrative: IT WAS THE FIRST LEG OF THE NIGHT. WE WERE DELAYED ABOUT 30 MINS FOR LOADING. WHEN GIVEN CLRNC; WE WERE GIVEN RWY 12 AND PLANNED ON THE HAMILTON 7 DEP. WHILE TAXIING OUT; GND GAVE US A LAST MIN RWY CHANGE TO RWY 30 WITH A NEW DEP OF GLANBROOK 1. WE HAD JUST FINISHED STARTING THE OUTBOARD ENGS AND WERE BACK-TAXIING TO RWY 30 AND WERE CONTINUING OUR 'BEFORE TKOF CHKLIST.' TWR CLRED US FOR TKOF AND WE CONTINUED WITH THE CHKLIST. MY FO SAID HE WAS FAMILIAR WITH THE ARPT AND READ OFF THE DEP INSTRUCTIONS FOR THE GLANBROOK 1. 1300 FT WAS SET IN THE ALT SELECT WINDOW. I REPEATED WHAT THE FO BRIEFED TO BE SURE THAT I UNDERSTOOD THE NEW DEP. WE FINISHED THE PROPER CHKLISTS AND TOOK OFF. THE FO SAID TO HOLD AT 1300 FT AND TURN TO 260 DEGS. I DID THIS; BUT WE SHOULD HAVE BEEN CLBING AT THE SAME TIME TO 4000 FT. WE GOT THE 'DON'T SINK' ON THE EGPWS. WE CAUGHT THE MISTAKE AND CLBED TO 4000 FT SHORTLY THEREAFTER. I SHOULD NOT HAVE LET MYSELF GET TOO RUSHED. I WAS AT AN UNFAMILIAR ARPT AND SHOULD HAVE REVIEWED THE NEW DEP WHEN GIVEN AND NOT RELIED ON MY FO. SUPPLEMENTAL INFO FROM ACN 785921: THE SID WAS BRIEFED AS CALLING FOR RWY HDG TO 1300 FT AND THEN TURNING TO A HDG OF 260 DEGS. BOTH PLTS WERE IN AGREEMENT OF THE BRIEFED PROC. AFTER TKOF; THE SID AND INITIAL CLB WERE FLOWN AS BRIEFED. SHORTLY AFTER LEVELING OFF AT 1300 FT; DEP CTL CLRED US TO CLB TO A HIGHER ALT AND A NORMAL CLB WAS INITIATED. DURING THE CLB THE DEP PROC WAS DISCUSSED AMONG THE CREW SINCE NO ONE FELT COMFORTABLE LEVELING OFF AT 1300 FT. UPON FURTHER REVIEW OF THE SID PROC; IT WAS DISCOVERED THAT 1300 FT WAS ONLY THE ALT TO START THE TURN TO 260 DEGS. IN ANOTHER AREA OF THE DEP CHART WAS A BOX STATING TO MAINTAIN 4000 FT. ALTHOUGH THERE WAS NO IMMEDIATE DANGER FROM THE BRIEF LEVELOFF AT 1300 FT; IF WE WOULD HAVE HAD TROUBLE CONTACTING DEP CTL; GND CLRNC COULD HAVE BECOME CRITICAL.
