Just a few comments, Paprika at least is already kennel trained, and trained to walk on a harness as well. She's also been extensively socialized with other pandas and people as well, so she'll likely settle in with Suva and her new keepers in excellent time.
As for transport, both girls will just be shipped air freight with Westjet Cargo, no keepers involved. Honestly neither facility really has to wait for the other to ship first, Valley zoo can house a minimum of 6 pandas, and I feel like Toronto has holding space to hold three at a time as well. They'll likely wait until October, as that's when the weather cools down and it is more conducive to shipping the pandas.
