No, you can keep 2 trout (cutties, rainbows, brookies or 2 browns if they are over 40 cm, or combo of one of the cutties, brookies or rainbows and one brown over 40 cm).
There is nothing better then trout from a mtn. lake/stream, the meat is so firm! Way better then the bow river swill or warm water stockies!! Of course I would hope that you wouldn't keep any tiddlers or smallish fish just to keep them?!

P.S I have one or 2 every 5 years or so...
