Continuing my response:
Assuming that the description below is correct for Chile, then profesor agregado = assistant professor and profesor auxiliar = adjunct professor

¿Qué es un profesor agregado?
El profesor agregado es también un profesor de planta, pero a diferencia del profesor titular, tiene la tarea de impartir varias materias y seguir las indicaciones de los titulares acerca de la manera en como dar el curso.
No hay que confundirlo con un profesor auxiliar, puesto que éste es aquel que se contrata por horas, no pertenece a la planta y su función es dar una materia que por ser demasiado especial no es dominada por ninguno de los titulares.

The three proposed translations are actually three different positions in Canadian universities, so it's important to understand what is meant in Chile by a "profesor agregado".
In Canada, there is a critical difference between an assistant professor and an adjunct professor: the assistant professor is a tenure-track position, whereas adjunct professor is not. Assistant professor is the entry-level position for professors with tenure track. Usually, this is the entry level after a person completed their PhD. They are then expected to become tenured within a period of time.

In contrast, as Ella noted, an adjunct professor is an external person to the faculty, not tenure-track, and under a contract with the university.

Some universities use the "lecturer" title to denote teaching positions that do not carry a research component, although it seems to me that "adjunct professor" is the more common usage in Canada.

So the answer is this: "associate professor" if you work for the university permanently and you are on tenure track; "adjunct professor" if you're on contract and not on tenure track.
