The Adelaide Hotel Toronto is a mixed-use skyscraper in Toronto, Ontario, Canada. It was built by Markham-based Talon International Development Inc., which is owned by Val Levitan and Canadian businessman Alex Shnaider. It used to be known as the Trump International Hotel and Tower Toronto. Using only the above description and what you know about the world, "Talon International is based in Markham." is definitely correct, incorrect, or inconclusive?
