Canucks are pretty decent, as good as any of the Turkish shotguns except for maybe the Weatherby guns. I've had a few Canucks and currently have an Enforcer as a "camp gun". It cycles, fires, and ejects fine.
The thing to remember is they are not "essentially" a Benelli or Beretta. They are unlicensed copies of a design whose patent has expired. The big difference is going to be around the changes that have taken place over time, the QA, the tooling used (some of it IS in fact original tooling purchased from the original manufacturer), the standards for fit and finish, the manufacturing process, etc. I had some better than others, and a few not so good.
But it's a Canuck, so you'll get better support through O'Dell than other clones and my experience has been good, heck my Enforcer is far nicer than my old Mossberg which did the same job. I'd definitely slap a "hunting barrel" on it and go pop birds if I didn't already have a Supernova.
For only a little bit more (maybe same price after rebate?) you could look at a Browning Silver semi-auto. You'll get an excellent shotgun with great support in Canada, and only give up the (IMO unnecessary) 3.5" chamber. My Silver is my favorite shotgun, and currently the only 12 gauge semi I bother to own.
