I don't think there are any refurbed SP2022's around. They are all brand new and they are all between $650 and about $850. The only "Certified Pre-Owned" guns (from SIG, coming in an orange rather than blue or black plastic case) I have heard of in Canada are the 220's and 226's.
What they show for CPO on the SIG website is here:

For those who are not that familar with the models, they are (left to right): 220, 226, 228, 229, 239, and a 229 in an orange case. (Note that those 229's have no rail... which is different from all of the 229's that have been imported into Canada in the last 18 months... except for the SAS which never have rails).
There were some "used" older SIG Pro's around.. SP2340 and SP2009, for example Dlask was selling some awhile ago... those were around $500. But CPO SIG Pro's of any vintage coming inthe orage box and the whole shebang... I have not seen that, at least in my neck of the woods. The reason is probably the same as why we have not seen any CPO 228's, 229's and 239's in Canada. The barrels on the guns originally sold to the police agencies would be prohib in Canada, and you would have to put a new barrel on it before you an ship it to Canada for sale to an individual... and the cost of doing that is going to pretty much defeat the purpose of the CPO idea (cheaper than new).
Then again... given the crazinss of our gun laws, and the pent up demand for "that which cannot be had".... if SIG took 500 CPO 228's and made new 106mm barrels for them... and put them into the Canadian market at the same price point as the brand new 229's.... they would sell them all right away no problem. The same probably goes for the 239's. (HINT HINT... some of you dealers and importers!)
Strangely, the SP2022's with the 106mm barrels do not seem to be moving all that swiftly. I'm wanting to get one, but there doesn't seem to be any shortage of people trying to sell them cheap.
