Alberta Reptile Laws

[FrogO_Oeyes]

Captive bred makes no difference. Black rats are specifically prohibited. Other subspecies are not, but anything which can be identified as "Elaphe obsoleta obsoleta", or a hybrid or intergrade thereof, is prohibited. Since black rats are not a distinct subspecies, but are actually dark northern populations of three different species, technically, all three species are prohibited by extension [but not in practice]:

Scotophis obsoletus [prohibited because E.obsoleta obsoleta cannot be reliably distinguished]
Scotophis spiloides [prohibited because E.obsoleta obsoleta cannot be reliably distinguished]
Scotophis alleghaniensis [prohibited because E.obsoleta obsoleta cannot be reliably distinguished]

So basically, if it looks at all like a "black rat", it's clearly illegal.
