The Government of Canada is investing 184 four-season lighted navigation buoys to be deployed in the St. Lawrence River shipping channel, between Québec and Montréal. The four-season buoys are unique in the world, designed using Canadian Coast Guard expertise to withstand the severe ice and tidal conditions found in the St. Lawrence shipping channel. They will remain in the water year-round and only require maintenance every two to four years. The four-season buoys will replace the seasonal navigation buoys operated by the Coast Guard that are currently deployed each summer and winter. The reduction in servicing and maintenance required for the new buoys, will allow the Coast Guard to achieve operational efficiencies. In July 2018, the Government of Canada awarded a contract of $12,351,790 (including taxes) to Canam-Ponts from Québec, Quebec, for the procurement of 184 four-season lighted navigation buoys. The contract includes options to acquire up to 204 additional buoys.
