The only legal way to ship anything from London to Mississagua is by shipping (flight wise)
The other way is to drive from London and deliver the animal right to the person.
Its only a 2 hour drive (or are you talking about the London England?) from London to Mississauga (if that) Just put the snake or herp in a deli cup, with holes in it and start driving~
I do that all the time. Heck I do that all the time for expos too~~
