When in doubt (especially for CBSA, along with US/Oz etc...), declare. Worst that can happen is you lose that raw duck and sausages you clearly shouldn't have and spend 30 mins in secondary.

And if you can carry anything explaining what you have, that can help. Like when I declared $790 or so of goods... wasn't an issue (not even secondary) as I had an itemized list.

Always rely on cash with backup card in S/M America, Asia and Africa. With a credit card for backup .. and normally hotel rooms. Sometimes ATMs aren't easy to find, or at least safe ones.
