That really sucks!! Wolf, I agree that asking it be mailed to you in a box would DEF be the thing to do next time
Do not ever underestimate the malicious glee and destructive potential of our posties here. They are not so easily cheated out of their spiteful pleasures.
For that matter, they could also use the "parcel locker", the one in the first picture, the one that Canada Post insisted be installed, but to do so would require those poor pitiful SOBs to walk an extra 14 paces. (7 each way)
I'm sure a Canada Post van has sufficient weight to make short work of any box constructed out of any material short of unobtainum alloy.
