The SLVC opens on Mother’s Day, and stays open until Mid-October. They provide visitors with estimated arrival times for freighters, great information about the shipping industry, and family friendly fun. When the SLVC closes, we rely heavily on the web page to determine when a freighter might arrive at the Soo Locks.

To provide information on boats all over the world, uses the onboard satellite trackers that are equipped on most boats. basic is free, but there are paid options. For the die-hard boat enthusiast, there is a smartphone app with a one-time charge ranging from $3.99-$5.99 depending on your phone. We’re going to focus on the features of the webpage, not the app, but they are similar.

Visit, locate the body of water you want to watch, and start finding boats! It’s really that easy. Zoom in and out to see the different shapes more clearly. Rest your mouse over an item for a short description of the boat, and click on the shape for more information. All shapes provide information, but green shapes are boats.

Each boat has an information card that tells up how fast the boat is going, its forecasted route, and vessel details.


This is all great information, but many people wonder about what time boats will arrive at the Soo Locks. Here is where our secret cheat sheet comes in handy to help you estimate arrival times. Remember this is only an estimation.
