Narrative:
We got a descent to 8000 ft, and promptly descended to the new altitude after the readback. After a few mins, I became concerned that the call may not have been for us. I am still not entirely sure. The problem is that our call sign is 'abc.' there was another flight by the call sign 'ab' on the same frequency. We are often confused with 'abb,' 'acc,' 'acb,' 'aab,' and about 20 other things I don't care to list. I am becoming very concerned about our call sign, especially when operating in or near canada, where so many conflicting call signs exist. Every single time I have ever been there, we have been confused with someone. So far, none of this has resulted in immediate danger, but I can't help but feel that a different call sign would alleviate the constant potential for confusion which now exists.

Narrative: WE GOT A DSCNT TO 8000 FT, AND PROMPTLY DSNDED TO THE NEW ALT AFTER THE READBACK. AFTER A FEW MINS, I BECAME CONCERNED THAT THE CALL MAY NOT HAVE BEEN FOR US. I AM STILL NOT ENTIRELY SURE. THE PROB IS THAT OUR CALL SIGN IS 'ABC.' THERE WAS ANOTHER FLT BY THE CALL SIGN 'AB' ON THE SAME FREQ. WE ARE OFTEN CONFUSED WITH 'ABB,' 'ACC,' 'ACB,' 'AAB,' AND ABOUT 20 OTHER THINGS I DON'T CARE TO LIST. I AM BECOMING VERY CONCERNED ABOUT OUR CALL SIGN, ESPECIALLY WHEN OPERATING IN OR NEAR CANADA, WHERE SO MANY CONFLICTING CALL SIGNS EXIST. EVERY SINGLE TIME I HAVE EVER BEEN THERE, WE HAVE BEEN CONFUSED WITH SOMEONE. SO FAR, NONE OF THIS HAS RESULTED IN IMMEDIATE DANGER, BUT I CAN'T HELP BUT FEEL THAT A DIFFERENT CALL SIGN WOULD ALLEVIATE THE CONSTANT POTENTIAL FOR CONFUSION WHICH NOW EXISTS.
