The sauna at 2199 Gottingen Street, Halifax, briefly advertised this name with a logo identical to GI•Joe in Montreal. Following representations by the lawyers for the Montreal business, the name was changed back to Seadogs Sauna before it opened.1
The Montreal sauna is at 1166 Rue St-Catherine; its website is here.
The previous bath in that location, TorpedoSaunaAndSpa, closed in March, 2020.2
In July, 2020, JoshuaErnst?3, "Josh Scotia" on Facebook, began inviting people to the page "GI Joe Halifax" with a name and logo identical to the sauna in Montreal, and announced that it would be opening at 2pm on September 17, 2020.
On September 12, 2020, he posted "Management announces it has chosen to revert to the Seadogs name." ... that is, the SeaDogsSauna name and logo used by DougMelanson starting in 2003.
