Narrative:

After landing on runway 6R at toronto, canada, I crossed the hold short line for runway 6L which was an active runway. I was able to stop short of the runway once I realized my mistake. I am used to operating at atl airport which also has parallel runways. However, there is a parallel taxiway in between the parallel runways in atlanta. There is no parallel taxiway in between runway 6L and runway 6R in toronto. As I cleared runway 6R, I mistakenly perceived runway 6L to be a taxiway. I think I could have avoided this situation by paying more attention to the airport layout chart in my commercial charts. I assumed I would pull off the runway and enter a taxiway which was not the case. Supplemental information from acn 564222: while the captain was taxiing, I was completing the after landing flow and checklist. I felt the aircraft come to an abrupt stop, and the captain asked me, 'is that a runway? What runway is this?' I looked up and saw that we had crossed the hold short line for runway 6L. The tower controller must have noticed, because I heard him instruct a turboprop taking off on runway 6L to abort. Tower reminded us, sternly, that we had been instructed to hold short, but to go ahead and cross and then contact ground. Perhaps if I had been heads up instead of running a checklist, I could have noticed our imminent incursion, and reminded him to stop and hold short.

Title: A CARJ CREW, AFTER LNDG AT CYYZ, CROSSED THE HOLD SHORT LINE OF THE PARALLEL AFTER BEING CLRED TO HOLD SHORT.

Narrative: AFTER LNDG ON RWY 6R AT TORONTO, CANADA, I CROSSED THE HOLD SHORT LINE FOR RWY 6L WHICH WAS AN ACTIVE RWY. I WAS ABLE TO STOP SHORT OF THE RWY ONCE I REALIZED MY MISTAKE. I AM USED TO OPERATING AT ATL ARPT WHICH ALSO HAS PARALLEL RWYS. HOWEVER, THERE IS A PARALLEL TXWY IN BTWN THE PARALLEL RWYS IN ATLANTA. THERE IS NO PARALLEL TXWY IN BTWN RWY 6L AND RWY 6R IN TORONTO. AS I CLRED RWY 6R, I MISTAKENLY PERCEIVED RWY 6L TO BE A TXWY. I THINK I COULD HAVE AVOIDED THIS SIT BY PAYING MORE ATTN TO THE ARPT LAYOUT CHART IN MY COMMERCIAL CHARTS. I ASSUMED I WOULD PULL OFF THE RWY AND ENTER A TXWY WHICH WAS NOT THE CASE. SUPPLEMENTAL INFO FROM ACN 564222: WHILE THE CAPT WAS TAXIING, I WAS COMPLETING THE AFTER LNDG FLOW AND CHKLIST. I FELT THE ACFT COME TO AN ABRUPT STOP, AND THE CAPT ASKED ME, 'IS THAT A RWY? WHAT RWY IS THIS?' I LOOKED UP AND SAW THAT WE HAD CROSSED THE HOLD SHORT LINE FOR RWY 6L. THE TWR CTLR MUST HAVE NOTICED, BECAUSE I HEARD HIM INSTRUCT A TURBOPROP TAKING OFF ON RWY 6L TO ABORT. TWR REMINDED US, STERNLY, THAT WE HAD BEEN INSTRUCTED TO HOLD SHORT, BUT TO GO AHEAD AND CROSS AND THEN CONTACT GND. PERHAPS IF I HAD BEEN HEADS UP INSTEAD OF RUNNING A CHKLIST, I COULD HAVE NOTICED OUR IMMINENT INCURSION, AND REMINDED HIM TO STOP AND HOLD SHORT.
