Firstly, I suggest you change the title. The word, symbol rather, "?" isn't very drawing. I personally suggest you purchase your enclosure from LLLreptile. But, as stated above, it depends what species and age of chameleon you're looking to house.
I think that for the animal, you should look to the site sponsors and have it shipped to you.
Before you have the animal shipped you should either go visit LLL (because, you are close) or hit their website and have them send stuff to you.
For adult veileds, I believe the standard is 24"x 24" x 48". As long as you are close to that, you should be okay on size.
You can buy animals from LLL (and they are a site sponsor) but keep in mind that they are not breeders and many of the sponsors are breeders. It's always better to go to the source.
That size would refer to 24" wide by 24" deep by 48" tall.
This size is fine for an adult male chameleon. The cages from LLL Reptile are very good. Easy to assemble and light weight. The shipping is a bit pricey to Canada when I order them but you won't have that issue.
