Three (3) types of infractions under the Provincial Offences Act (known as P.O.A) (Part I,II & III under the P.O.A):

Part I – Alleged Infraction (normally moving violation)  results in a ticket and a set fine is associated with alleged infraction (ie speeding, etc).

Part II- Parking Tickets (alleged parking infractions).

Part III- Alleged Infraction results in a summons to court.  These infractions may involve jail and are serious infractions, without a fixed fine.

If you are interested in reviewing the entire P.O.A., it is a lengthy piece of legislation but it will become a cornerstone of any arguments in the Ontario Courts- see: Provincial Offences Act
