Sydney Mines (Mi'kmawi'simk: Klmuejuapskwe'katik; Scottish Gaelic: Mèinnean Shidni) is a community and former town in Cape Breton Regional Municipality, Nova Scotia, Canada.

Major Timothy Hierlihy and his regiment on board HMS Hope worked in and protected from privateer attacks on the coal mines at Sydney Cape Breton.

"[5][6] A few years into the war there was also a naval engagement between French ships and a British convoy off Sydney, Nova Scotia, near Spanish River (1781), Cape Breton.

Manufacturing enterprises included corrugated steel culverts and the British Canadian Co-operative Society Limited, operating a dairy and a bakery.

As with the rest of Nova Scotia, Sydney Mines experiences seasonal lag and has a relatively slow, cool start to summer in June and early July.

Also, onset of the Bermuda High in July brings warm southwest winds to the area, which dominate the remainder of the summer into September.

With an average daily high temperature near 25 °C (77 °F) in July and August, conditions are quite comfortable, albeit very humid at times.

Daytime highs during the winter usually stick around minus 2 degrees Celsius but the fact Sydney Mines lies around the polar jet stream causes it to experience arctic outbreaks and very warm thaws.

Cold arctic temperatures meet up with the warm Gulf Stream and form one of the most powerful storms in the world.

In front of Jubilee Elementary on Main Street, there is a bronze statue of Johnny Miles in a running pose.
