IOTL Cape Breton, which would become the center of the Gaelic speaking community in Canada, was a separate colony from Nova Scotia briefly from after the ARW until 1820.
If it's not reintegrated into Nova Scotia in 1820, it would become a majority Gaelic speaking colony.
The addition of a fourth small colony could lead to a greater impetus for Maritime integration, and a Maritime Union (perhaps including Newfoundland) could emerge before Confederation. In this Maritime Union, Gaelic could be an official language.
When the Maritimes and the Canadas Confederate, Gaelic could be Canada's third official language. Constitutional official language policy (government services to be provided where numbers warrant) would lead to geographical concentration over time and there could be minor Gaeltachts on the prairies, the west coast, yukon, Southern Ontario and the Eastern Townships of Quebec in addition to the major one on the east coast.
