It sounds like runway time is the only thing that messes up your day. S.
Nah, that's just one of the many things.
Far too little tin is being pushed at YYZ...
When I see the way movements are being done in SFO with close parallels that cross... and they manage it with one tower controller and one ground controller I wonder why we can't get SIGNIFICANTLY better performance out of YYZ.
Ridiculous generalization! You can't compare any US airport with YYZ unless it has exactly the same layout. You land on the 28s at SFO and go straight into the ramp and its a short taxy to the 1s with the occasional taxi to a 28 for a heavy that needs the length. There is almost no complexity there. Yes, there's a high energy intersecting operation, but that's it.
I have never seen a flow program in place for YYZ citing low ceilings and yet SFO, SEA, LAX, EWR, JFK, LGA and BOS regularly have restrictions in place for this. On a clear day they may appear to be more efficient but when the weather craps out you've instantly got serious, schedule destroying delays.
How many of these busy US airports use mixed mode as their primary operation? That's landing and departing the same runway in case you weren't aware of the term. The tower has to play the hand its given. Arrival spacing has to be spot on to maximize throughput. A mile less than we need, no departure. A mile more than we need, wasted mile.
Ideally we want to issue take off clearance when the arrival is 2.5-2.0 miles from touchdown. That's the sweetspot and there's not much room for error. If the preceding arrival dogs it, you go around. If the departure dogs it, you go around. Over my nearly 30 years in this job I have noticed a reduction in the performance of aircrews. Its getting to the point where we don't trust you to do what's needed and will let a tight one go by rather than push it. We get no thanks when we push it and if it goes sideways we get asked why we pushed it. So why do it?

Not quite sure what is meant by "too little tin" when YYZ is in the top 15 airports worldwide (movement wise) and at a full triple can shift 70 arrivals an hour...plus whatever departures (Cossack can give a better number than me).
And a dual can do close to 60 arrivals, more if flow penalizes the departures. Hourly totals are regularly over 100 these days and on some days you're hardly breathing hard. On others you have to fight for everything and feel like you've been through the wringer.
The runway/taxiway layout is the main cause of grief. Long routes to/from the gate with lots of conflictions, then a long line when you get there. Also it seems that if there isn't a line up, a lot of crews aren't ready when they get there, even after a 2 mile taxy. Get your own house in order! You're delaying everyone behind you while you taxy slow hoping to be ready by the end of the runway.
I tried to explain earlier why long lines happen at 05/23 and there's no sure way of solving it. Taking 5 controllers each from the above mentioned US airports and putting them in the tower here would not move the traffic any better using the rules we have to abide to. Its just a fallacy.
Scheduling needs to be looked at and that's GTAA not NavCan. Arrivals all wanting in at the same time and big departure bulges. Yesterday evening for example:
At 8:45pm there's an unforecast wind shift. 020/10G18 with a 2000' wind of 290/20. We've been on the 24s all day but what should we do now? We went to the 33s to avoid operating with any tailwind.
Between 9:00-9:15 there are 32 scheduled departures and no surprise, very soon there's a long line waiting to go, and they're going fast because we're using visual departures, but there are still guys dragging themselves onto the runway like they're the only ones there.
The 33s is a shitty configuration as the terminals are on the other side of the departure runway from the arrival runway. You may have noticed the increased use of the F-C4-06L route. Runway crossings are being avoided wherever possible to keep the departure rate up. Yes its a long taxi but there's more chance of continuous movement to the gate. There is, however, a price to pay: 121.9 (me last night from 9:00-10:30) gets very busy. Every departure and almost every arrival goes through south ground.
Then the noise card is played and we have to land on 06R and the last arrivals on 33L are now mixing it with the first arrivals on 06R and we still have 10+ in the line for departure.
Please avoid the sweeping generalizations. They're not valid for the reasons MaC, Braun and I have tried to outline. Enjoy your break MaC, but if some of the above are to be believed, you'll be lucky to leave at all.
