The restrictions are off - no problems. However, your problem may exist in another form. If you are planning to base yourself in Vancouver in October you will have a hard time finding steelhead. The closest river with steelhead in October is the Thompson - a 3 hour drive - but
, as of now it is closed and doesn't look too good for opening anytime soon
If you are coming to BC to fish for steelhead in October you need to be in Skeena country! That is at least a 15 hr drive away from Vancouver. You would want to base yourself out of Smithers of Terrace - not Vancouver.
I hope you can work it out - Skeena country is awesome.
