Narrative:
After departing cyhm en route to pit our clearance was to fly the hamilton 6 departure and maintain 4000 ft. I ran the climb checklist, called 1000 ft to go to leveloff, and replied to ATC to proceed direct eri. I told the first officer I was leaving communication #1 to call our times into company. When I returned to communication #1 we were climbing through 4500 ft. Before I could ask what our new assigned altitude was, toronto center called and asked what altitude we were climbing to. I asked the first officer what altitude we were assigned by ATC, he replied I thought we were cleared direct eri up to 12000 ft. I then replied to ATC thinking we were assigned 12000 ft while off communication #1, that we would like to take 12000 ft as our final altitude. ATC said our clearance was to maintain 4000 ft as per the SID for noise abatement, and then assigned us a new altitude of 6000 ft. There was no conflict with any other aircraft in the area and after further discussion with the first officer I found out that he flies the same route twice a day and the standard ATC directions are to fly direct eri and climb and maintain 12000 ft. The flight was his second time there in 3 hours and he thinks the clearance was for the earlier flight. Another contributing factor was that I did not catch us passing 4000 ft and question the first officer.

Title: LTT OVERSHOT ASSIGNED ALT WHILE ON THE HAMILTON 6 SID.
Narrative: AFTER DEPARTING CYHM ENRTE TO PIT OUR CLRNC WAS TO FLY THE HAMILTON 6 DEP AND MAINTAIN 4000 FT. I RAN THE CLB CHKLIST, CALLED 1000 FT TO GO TO LEVELOFF, AND REPLIED TO ATC TO PROCEED DIRECT ERI. I TOLD THE FO I WAS LEAVING COM #1 TO CALL OUR TIMES INTO COMPANY. WHEN I RETURNED TO COM #1 WE WERE CLBING THROUGH 4500 FT. BEFORE I COULD ASK WHAT OUR NEW ASSIGNED ALT WAS, TORONTO CTR CALLED AND ASKED WHAT ALT WE WERE CLBING TO. I ASKED THE FO WHAT ALT WE WERE ASSIGNED BY ATC, HE REPLIED I THOUGHT WE WERE CLRED DIRECT ERI UP TO 12000 FT. I THEN REPLIED TO ATC THINKING WE WERE ASSIGNED 12000 FT WHILE OFF COM #1, THAT WE WOULD LIKE TO TAKE 12000 FT AS OUR FINAL ALT. ATC SAID OUR CLRNC WAS TO MAINTAIN 4000 FT AS PER THE SID FOR NOISE ABATEMENT, AND THEN ASSIGNED US A NEW ALT OF 6000 FT. THERE WAS NO CONFLICT WITH ANY OTHER ACFT IN THE AREA AND AFTER FURTHER DISCUSSION WITH THE FO I FOUND OUT THAT HE FLIES THE SAME RTE TWICE A DAY AND THE STANDARD ATC DIRECTIONS ARE TO FLY DIRECT ERI AND CLB AND MAINTAIN 12000 FT. THE FLT WAS HIS SECOND TIME THERE IN 3 HRS AND HE THINKS THE CLRNC WAS FOR THE EARLIER FLT. ANOTHER CONTRIBUTING FACTOR WAS THAT I DID NOT CATCH US PASSING 4000 FT AND QUESTION THE FO.
