G'day eh. I have an adult B&W and just picked up two new juviniles from other herpers(Red and B&W Argentines). Bad news though. There are no Canadian breeders for tegus of any sort. It is a safe bet that all for sale are imports. Sadly because they are not the easiest of animals to breed, especially in this climate where outdoor enclosures are not practical, the logistics for captive breeding oare quite unpracatical, and the cost for such animals would be quite high. As such imports will likely be the norm here for a long time. Being CITES II they are not difficult to bring across the border if you are willing to pay the money.
