How are the runways operated at Toronto Pearson? I have a sort of technical question regarding the operations of runway systems at larger airports, specifically at Toronto Pearson (satellite view here). As far as I can see, the airport has 5 runways: 05, 15L/R, and 06L/R.

Since RW05 and RW15L/R intersect it is clearly infeasible to operate RW05 at the same time as RW15L / RW15R. As for the rest, there are several ICAO guidelines regarding parallel or near-parallel runways. What do those restrictions imply regarding simultaneous operations?


Is it possible to operate RW06L and RW06R simultaneously, maybe in a segregated mode of operation? What about RW15L/R?
Similarly, can runways 15 and 06 be operated simultaneously?
According to Toronto Pearson's official website, the airport operates in four main configurations, this is what they look like:





Also judging by the satellite imagery, CYYZ is LAHSO enabled, that is the intersecting runways (05 and 33L, for example) can be used simultaneously. (It resulted in a near-miss back in 2002.)
