Suther, maybe you should read all the posts before you open your yap. The OP also asked about fishing in other areas ie "Im thinking is there any locol stream/ creek that is in vancouver bc", this would be covered by the Freshwater regs, hence the link. OP originally asked about Stanley Park so I also included the DFO link, that's for saltwater okay. I also recommended phoning both to make sure as well as the city to see if there were any special restrictions.
You specifically said "According to the online regs you can fish there" Which means you are refering to a specific location, not giving general info.
Also, the link you provided for the DFO details what salmon you can retain in FRESH WATER systems.
Finally, the city doesn't have jurisdiction over fishing regulations, thats provincial jurisdiction.
So how about YOU dont open YOUR yap when YOU dont know what YOU are talking about.
