Where are you looking Rendra?
We are probably a week or so from seeing them show up in Saanich Inlet(hoping they show!!). The Vic gorge doesn't follow the same trend that the ECVI seems to and there have been some recent reports.
If you see anything, even just bait balls, etc, map it! :

Good luck looking!
