Section 1 (1) of the Wildlife Act defines "controlled alien species" as:
(a) a species designated by regulation under section 6.4 of the Wildlife Act as a controlled alien species, and
(b) hybrid animals and fish that have an ancestor within 4 generations that is a species designated as a controlled alien species.
Note: all subspecies within the species listed in Schedule 1 and 2 of the Controlled Alien Species Regulation are also considered CAS.
For example,

A dwarf reticulated python is considered CAS because it is a subspecies of Python reticulatus (reticulated python);
A Burmese python is considered CAS because it is a subspecies of Python molurus (Indian python);
A dingo is considered CAS because it is a subspecies of Canis lupus (grey wolf).
