VIVA green is by Fairview and goes North(east) to Hwy 7. Transfer to another bus either the 1 (I believe) or VIVA purple Westbound to get to the outcall, I mean Hwy 404 area.
When you take VIVA you get your ticket at the automated kiosk, big blue thing, can't miss it. If you have a Presto card you can tap on at the kiosk instead. You don't show the driver your ticket/presto card, he doesn't care if you paid or not, however ticket enforcement officer do if they happen to board the bus.
As for time, I haven't a clue. Going across Hwy 7 should be fast since that part of the city has dedicated transit lanes now so traffic should be less of an issue.
