Actually, the markings are effective in YYZ if you pay attention and don't do unnecessary things at critical times. Of course there will be no TSB report for these incursions(although you might post the internal AC report for us and SFO ones as well, for safety reasons of course), but.....
As a general investigation not directly related to but similar to YYZ events....pretty much the top recommendation is...
"Recommendations
The SCRI recommends that:
Transport Canada focus on developing preventive strategies for runway incursions that result from pilot deviations. Immediate action should be taken to disseminate, on a recurring basis, information to pilots about human performance vulnerability to error due to workload, and potential distractions associated with the performance of cockpit tasks."
