How about four or five days up in the straits, then take the ferry for the balance of the trip to Vancouver Island in the Ucluelet or Tofino area.
I know you said you prefer salmon & steelies. Here is another thought. How about a few days in Cabo. June and July are prime time. If you've never caught any saltwater fish like tuna, dorados, jacks, roosterfish etc, you'd be in for a real great time.
Have a great time.
