We have several sources for current preditions. One is Ports and Passes as mentioned by Nsail.
We also have an application on our iPad called Navimatics. This is a charting application, not a navigation application (plotter). Navimatics has tide and current markers on the chart that when you tap them you get a table that you can set for the date and time you want.
Navimatics also incorporates Active Captain. So for Malibu Rapids at the entrance to Princess Louisa, there is an Active Captain entry that calls out the current speeds and the reference times to Point Atkinson, the same times as Nsail posted above.
We also use the Canadian Current Atlas with the relevant annual Washburn table booklet. This covers the Gulf Islands and Strait of Georgia but I don't think it includes Jervis Inlet. (The Washburn Table is now published as the Waggoner Table, but it's the same thing.)
We also have the big Capt.Jack's Current Atlas for the Pacific Northwest that covers the waters from Queen Charlotte Sound to Puget Sound. No longer in print, the annual current tables are still published. The Atlas itself can still be obtained used from places like Amazon, but the prices can be pretty steep.
