Gary, you can sell the parts yourself here in our classifieds or on eBay... and the frame can be pounded into scrap metal with a two pound sledge if there is no other legal alternative...
I may be wrong, but it is my understanding that long barreled Lugers are legal for possession in Canada... perhaps you can have it rebarreled to a longer length rather than parting it out.
I guess we would have to know what you are trying to accomplish in order to advise you properly.
The only Luger parts dealer that I know of in Canada is Marstar... Here is the link from our Links and Resources page.
