AntsCanada is a great gateway into antkeeping but I would beware about the GAN.
I connected with someone listed on the GAN in my state. As I was working out the purchase and delivery, there were a lot of red flags, which I ignored because I trusted AntsCanada. The person said that they already gave away the species I wanted, but maybe I would be interested in other species instead. They pushed a species which isn't really known to native to my area, but he insisted he found them locally. They aggressively tried to upsell me on expensive extra supplies they said were critical to the care of this species. When I got my ants, they were shipped from several states away.
I reported this to AntsCanada. I'm not sure what happened, but I recently tried to get a different queen from GAN and I ended up talking to the same person under a different identity.
I'm sure there are some great people on GAN, just beware.
I ended up getting a queen from Atlantic Ants. It did ship across state lines, but the species is one that's ubiquitous in my region.
