They haven't changed the frequency recently, but it's been listed as 8 minutes south on Broadview b after 7:15 AM and before 10AM and 10 minutes after for a while (it used to be 2 to 4 minutes with the old cars).
However, looking at the data at Transee, I'm surprised to see there's a change. There were some extra cars scheduled during the King/Shaw diversion, but as of October 6, there's 3 less cars scheduled between 8 AM and 9 AM. On the other hand, there seems to be more missing cars before October 6 - perhaps it's just more regular now?
There's certainly been a schedule change; perhaps it's simply more predictable now.
