Shubenacadie Grand Lake

Shubenacadie Grand Lake is a large Canadian lake straddling the Halifax Regional Municipality and Hants county on mainland Nova Scotia.

It drains into the Shubenacadie River at its northeastern outlet.

The lake is the seventh and largest lake in the Shubenacadie Canal system and is located between Lock 5 and 6.

Shubenacadie Grand Lake hosts two provincial parks, Laurie Provincial Park and Oakfield Provincial Park, both on its eastern shore.

Shubenacadie Grand Lake has been under blue-green algae advisories during recent warm seasons due to harmful algal blooms. Deaths among dogs in Atlantic Canada have been associated with their consumption of cyanobacteria toxin-contaminated water. An increasing frequency of algal blooms may be attributable to the effects of climate change.
