Canada Post with Signature... use a trigger lock, no live ammo with it... but as said above, Canada Post does not require contents declaration when shipped within Canada... many guns ship Expedited (ahem)... also, remove the bolt on bolt action rifles, and remove scopes and rings and wrap separately in the box, bubble or foam wrap everything individually and then pad the box well with crumpled paper so that nothing can shift around, I use packing tape on 100% of the box and particularly the ends incase it is dropped. Also, if you use an actual firearms box, make sure that you paper wrap it to cover all firearms related logos... intentional damage has occurred by anti-gun CP employees... why take a chance.... I make my shipping labels in WORD in large bold font and print the label, then tape the label on by wrapping the packing tape completely around the box... you won't have a label scrapped off this way and it will be clearly legible.
