I would be concerned with section 13.1 of the CAIA with regards to an "invalid insurance card".
So say you put your new card in the vehicle but it is not valid yet, and your old one is still valid. Or the new one becomes valid, but your old one is still in the car and it is invalid now. In theory you can get a $10,000 fine for this!
Possession, use, sale, etc., of false or invalid insurance card 13.1 (1) No person shall,
(a) have a false or invalid insurance card in his or her possession that he or she knows or ought to know is false or invalid;
(b) use a false or invalid insurance card that he or she knows or ought to know is false or invalid;
(c) sell, give, deliver or distribute a false or invalid insurance card that he or she knows or ought to know is false or invalid; or
(d) produce for inspection any other evidence, that he or she knows or ought to know is false or invalid, that the motor vehicle is insured under a contract of automobile insurance.
Offence (2) A person who contravenes this section is guilty of an offence and is liable on a first conviction to a fine of not less than $10,000 and not more than $50,000 and on a subsequent conviction to a fine of not less than $20,000 and not more than $100,000.
