Look at it this way. The bi-law's in toronto are 3 meters for a snake. How many people in Toronto own retics, burms, anacondas etc. I believe the law for lizards is 2 meters, and you've got god knows how many iguanas, and monitors.
Be a responsible pet owner, and i highly highly doubt you'll have any problems whatsoever. If you live in a rented dwelling, if your landlord comes in just cover up the animals.. He/she isnt allowed to snoop through your belongings. Trust me you wont have problems as long as you continue to be a responsible pet owner.
