Narrative:
Landed on runway 24R at cyyz. Cleared runway at taxiway C4. Past experience, taxi route was always txwys 'D-B (or a)' to ramp. Taxi clearance this time was taxiway east short of taxiway south. Quick glance at airport chart saw that taxiway east paralleled runway 33R (as does taxiway B). Missed turn at taxiway east and was just short of runway 33R when I realized I had missed taxiway east and at that same moment ground cleared aircraft behind us to cross runway 33R. Continued across runway 33R and as soon as ground finished clearance to aircraft behind us, I requested further taxi clearance. Runway 33R was (as most often) an inactive runway at this time. Preconceived mental picture of normal taxi route, txwys B, a, and east all paralleled to runway 33R. Frequency congestion at the moment of discovery coupled with clearance of aircraft behind to cross runway 33R and possibly the location of taxiway east sign at the large deicing area (as I did not notice the sign) all combined to contribute to their error. Supplemental information from acn 537502: stopped aircraft on taxiway D short of taxiway B and requested additional taxi instructions. Was reclred to taxi.

Title: RWY INCURSION WHEN A B737-400 FLC CROSSES RWY 33R WITHOUT CLRNC AFTER PASSING THEIR CLRED TXWY E AT CYYZ, ONTARIO, CANADA.
Narrative: LANDED ON RWY 24R AT CYYZ. CLRED RWY AT TXWY C4. PAST EXPERIENCE, TAXI RTE WAS ALWAYS TXWYS 'D-B (OR A)' TO RAMP. TAXI CLRNC THIS TIME WAS TXWY E SHORT OF TXWY S. QUICK GLANCE AT ARPT CHART SAW THAT TXWY E PARALLELED RWY 33R (AS DOES TXWY B). MISSED TURN AT TXWY E AND WAS JUST SHORT OF RWY 33R WHEN I REALIZED I HAD MISSED TXWY E AND AT THAT SAME MOMENT GND CLRED ACFT BEHIND US TO CROSS RWY 33R. CONTINUED ACROSS RWY 33R AND AS SOON AS GND FINISHED CLRNC TO ACFT BEHIND US, I REQUESTED FURTHER TAXI CLRNC. RWY 33R WAS (AS MOST OFTEN) AN INACTIVE RWY AT THIS TIME. PRECONCEIVED MENTAL PICTURE OF NORMAL TAXI RTE, TXWYS B, A, AND E ALL PARALLELED TO RWY 33R. FREQ CONGESTION AT THE MOMENT OF DISCOVERY COUPLED WITH CLRNC OF ACFT BEHIND TO CROSS RWY 33R AND POSSIBLY THE LOCATION OF TXWY E SIGN AT THE LARGE DEICING AREA (AS I DID NOT NOTICE THE SIGN) ALL COMBINED TO CONTRIBUTE TO THEIR ERROR. SUPPLEMENTAL INFO FROM ACN 537502: STOPPED ACFT ON TXWY D SHORT OF TXWY B AND REQUESTED ADDITIONAL TAXI INSTRUCTIONS. WAS RECLRED TO TAXI.
