Where did you buy the gun?
You could also try contacting C.A.S (Canadian airgun supply) I believe they are the ones that are bringing G&Gs into Canada.
Although, sorry to say this, if four weeks have already passed since the purchase, you might be out of luck.
Worst case scenario, go and get yourself age-verified and you will have access to the parts classifieds section here, there are a number of replacement bodies available, plastic or metal.
All the best,
