Why does the reason for the suspension matter so much?
Because section 53 contains two separate penalty schemes and the difference between them is a factor of five at the bottom and ten at the top.
An ordinary suspension, whether for unpaid fines, accumulated demerit points, a medical reason or an administrative one, engages section 53(1): a fine from $1,000 on a first offence. A suspension under section 41 or 42, which are the suspensions that follow Criminal Code convictions connected to driving, engages section 53(1.1): a fine from $5,000 on a first offence and from $10,000 on a subsequent one.
Subsection 53(1.1) also closes an obvious argument. It applies where the licence is suspended under section 41 or 42 even if it is under suspension at the same time for any other reason, so a driver who is suspended both for a criminal matter and for unpaid fines does not get the lower penalty by pointing at the fines.
The practical consequence is that the first thing to establish is which suspension you were actually under on the day. Drivers are frequently under more than one, and the paperwork explaining each of them arrives at different times from different places.
