In winter, keeping the St Lawrence Seaway’s numerous locks and tight navigational channels moving becomes all the more challenging. Operating the gates of the locks becomes difficult, with ice building up the sensitive machinery and their tight fittings. As a result, the Seaway authority shuts down until such time that the operation of the locks, and navigation of the channels can be reliable and safe.
When the seaway shuts down, it effectively shuts down nearly all of shipping on the great lakes and its connecting rivers. Typically, the seaway shuts down in late December, 26-31, and reopens in late
March, 18-25. The closure typically means that all commercial vessel traffic cannot go further up the St Lawrence River than Montreal, and those ships caught in Lake Ontario, stay there. Some ships may still operate on Lake Superior, Lake Michigan and Lake Erie but traffic is curtailed considerably due to weather and ice conditions, but mostly because of limited cargo opportunities.

Many "lakers" will switch from active service into "winter lay-up”, or “winter works” period. Winter work is a necessary part of keeping Canada’s aging fleet going. Pushed hard the rest of the year, the old ships needs considerable care to make them pass the regulator’s scrutiny in early March. Dry dockings, surveys, steelwork, machinery rebuilds fill the “Winter Work List” of many vessels. The manpower at the local repair outfits is stretched thin during these times and finding elusive parts or skilled labour for old machinery is a big challenge.

I remember having a discussion about the application of hull paint at the Ocean Group shipyard in Iles aux Coudres, Quebec. The weather was brutal cold, but we had a schedule to keep, so we had to contact the paint manufacturer to find out how low a temperature we could still apply their product; with the outside temperature at -21C degrees we would be fine to paint, barely.
Not all ships need extensive work, and often the ships are winterized, and tied up to berths all over the Great Lakes ports, Port Colborne, Montreal, Hamilton, etc. These ships are securely moored and winterized; the crew is signed off for the winter.

Once the second week of March rolls around, the tired shipkeeper can starts to feel normal again, with the arrival of some crew members. The crew members are there to prepare the ship for the upcoming sailing season. This period is often referred to as “fit out”. The engineering teams are stressed at this time, wrapping up the winter work list maintenance projects, or otherwise reactivating the old bones of a great dame.
At this time of year, regulators are overwhelmed with surveys and certification exercises and a great deal of paperwork is shuffled around. There is usually a constant parade of officials and certification exercises on the ship.

With the reopening of the Seaway in late march, the “winter lay-up” ends, and that year’s Great Lakes Shipping Season begins. The first ship through various locks, in the “Spring”, is usually well celebrated by numerous organizations, garnering a crowd, and the media, to cover this special event. The milestone is usually marked by the awarding of a Top Hat or a Cane or some kind of symbol, celebrating the end of another long Canadian winter.
