Narrative:

On taxi for departure, inadvertently taxied a short distance beyond hold short line. Tower sent arriving aircraft around. This is a somewhat unusual taxiway layout, parallel taxi route turns left toward displaced threshold, then back right and left again to full length. I expected to see hold short lines when pointed toward full length point of runway. I may have missed seeing the actual hold short point as we were in the turn, or during a momentary master caution/ECAM warning. Regardless, I never saw the line and still don't know exactly where it is, since it's not charted. I will certainly be looking for it next time I depart yyz!

Narrative: ON TAXI FOR DEP, INADVERTENTLY TAXIED A SHORT DISTANCE BEYOND HOLD SHORT LINE. TWR SENT ARRIVING ACFT AROUND. THIS IS A SOMEWHAT UNUSUAL TXWY LAYOUT, PARALLEL TAXI RTE TURNS L TOWARD DISPLACED THRESHOLD, THEN BACK R AND L AGAIN TO FULL LENGTH. I EXPECTED TO SEE HOLD SHORT LINES WHEN POINTED TOWARD FULL LENGTH POINT OF RWY. I MAY HAVE MISSED SEEING THE ACTUAL HOLD SHORT POINT AS WE WERE IN THE TURN, OR DURING A MOMENTARY MASTER CAUTION/ECAM WARNING. REGARDLESS, I NEVER SAW THE LINE AND STILL DON'T KNOW EXACTLY WHERE IT IS, SINCE IT'S NOT CHARTED. I WILL CERTAINLY BE LOOKING FOR IT NEXT TIME I DEPART YYZ!
