Thats partially true.
In GTA the bylaw says
No snakes over 3 meters, which is about 9 ft
and no lizards over 1 meter, about 3 ft
You can't even keep iguanas or larger monitors.
If you live further south in Brantford ontario
you can keep any size colubrid, for example
Tiger rat snake, but you can't keep a sand boa.
Their bylaw says no boas or pythons. Also you
can't keep monitors or crocs, obviously crocs, but
ackies? Ackies are way less dangerous than alot
