Terms of use
Toronto Through Time (torontothroughtime.com) is a free map of Toronto's history, run by Andreas Duess in Toronto, Canada. By using the site you agree to these terms. If you do not agree, please do not use it.
What the site is, and is not
The site is a history project made for learning and enjoyment. It is a model, not a survey. Many building years are best guesses, old maps were read by computer, and there are mistakes. How it was made explains what is known and what is guessed.
Do not rely on the site for anything that matters: buying or selling property, legal or planning questions, heritage decisions, finding your way, or planning a trip. The positions of buses, streetcars and bikes and the weather come from other services and can be late or wrong.
Offered as it is
The site is provided "as is" and "as available", with no promise that it is correct, complete or always online. To the extent the law allows, Andreas Duess is not responsible for any loss or harm that comes from using the site or relying on what it shows.
