@Lambic, depending on your risk tolerance, you may wish to consider buying a used kit, as suggested by @pres589 above.
For example, there's a complete kit offered in the PF Marketplace:
Pentax K-5 II Kit + (1400 shutter count) - PentaxForums.com
K-5 II, DA 18-135mm and DA 50/1.8. That would be a great compact travel kit. The DA 18-135mm is well-regarded by many forum members here, it's water-resistant, and gives a good range of focal lengths. The K-5 II is also a very fine camera, albeit two generations old now.
Please note that I'm not associated with the seller of that offer, nor am I vouching for the credibility of the seller or the quality of the gear. It's just an example of what could be found on the used market.
For used camera stuff you buy from US sellers, you will not pay any duty but you'll likely pay Canadian HST on imports valued greater than about CAD $100.
