If you are saying Flight Aware's data is inaccurate, ok.
What matters is the scheduled gate departure times and scheduled gate arrival times, which is what I provided. On the specific flights that you quoted, AC's and WS's schedules are essentially the same. Even on FlightAware's own data for each of those flights (which is not always accurate, but let's assume it is), the average gate arrival delay for both AC119 and WS717 is 20-40 min.
Looking at the past 10 days.
AC119 is -12, -4, -27, -20, -114, -18, +1, -17, -9, -36. Average Schedule Adherence -25.6 minutes. Removing the highest and lowest as outliers (-114, +1) and we get an average of -17.88 min.
WS717 is +12, -5, -43, -59, -20, -14, -2, +7, 0, -88 Average Schedule Adherence -21.2 minutes. Removing the highest and lowest as outliers (-88, +12) and we get an average of -17 min.
Again I'm not saying AC is doing a great job in this regard - they have lots of room for improvement. But these reports and statistics don't always tell the complete picture. If AC blocked AC119 at 10 hours, it would be on time over 99% of the time. But that wouldn't be very useful for passengers.

That is also assuming that you take off to the west in YYZ and land to the west in YVR. If you need to turn, you will have less than 4 hours. The crusing speed of a 737 is 583 mph. This is not achieved for the whole flight since you must climb and descend. The average speed is probably closer to the 521 mph. Westbound flights must also fight a headwind, reducing their average speed further. I believe the published block times of 4:50 to 5:15 are more accurate compared to the 4:23 that you quoted.
