Can anyone identify this disease? I am reluctant to treat until I know what it is.

Often bacterial or fungal, treatment is based on getting the treatment on the plant before you see the damage. Treatment now, after seeing the spots will be aimed at protecting the new leaves.

After researching it appears that what our potato plants have is "early blight".
