Here’s a small ad from the October 18 1929 edition of the Toronto Globe for an upcoming dance performance at Massey Hall.

La Argentina was the stage name of Antonia Mercé y Luque (1890-1936), a Spanish dancer who was, not surprisingly, born in Argentina. She made six transcontinental tours of North America, and was performing as late as the spring of 1936.
She passed away on July 18, 1936, in Bayonne, France, apparently of sudden heart failure. YouTube has a short video of her performing.
