Very informative tour - Tom gave an excellent presentation of the technical, historical and social aspects of building the "Underground City" of Montreal. He welcomed questions and provided comprehensive answers. He used the underground displays to give us a succinct history of Quebec and Montreal. While using the Metro, we heard about its technical aspects through design construction and operation. We enjoyed it very much.

Great Way to Meet Montreal - This was a perfect tour to kick off an exploration of Montreal. We got some history and architecture as well as a working understanding of the Metro and the underground city. By the end of the tour we were ready to head out on our own. We will definitely seek out Thom for future tours around Montreal.

The best tour and guide!!! - Tom truly is the best tour guide I have ever had and his underground downtown tour is one of the best tours I've done (and I do them in every city I travel to). He was full of historical and Montréal knowledge and really brought the city to life for me and my family. His love for his city was contagious. I highly recommend this tour to anyone coming to Montréal for the first or 20th time!!!
