without it being a complete gun they wont be able to "test" it anr as such it may get seized there are also alot of other factors involved in the determination of "firearm" "replica" "restricted" and "unrestricted" if i wer you id go to the cbsa website and look up the legislation read it and try to understand it befor you try to import anything especially frames lower recivers or full guns.
after you have a good understanding of tue definitions of things then i would email them not call and get everything in writing then once you get the "ok" from a seinor member of cbsa not some phone jockey make sure you get them to fax or mail you a letter with their signature and id number on an official cbsa letterhead then order your product.
from someplace thats not evike lol
