Another Canadian here with tips... I'd actually suggest shipping it airmail parcel post. It's never more than a $1 or so more than surface (and for me surface does take the full 4-6 weeks!) so i'd rather pay the extra $1 and get it sooner. Never mark the value as more than it's worth (we will often pay taxes on the value at the border.) If possible, it's appreciated if you mark it as a gift. If you have any more questions feel free to pm me!
