Even though the Crown has the burden of proving your guilt at a trial, the Crown will not necessarily call all the evidence that might help you explain your situation or answer the charges you face. The manner in which you try to defend yourself without a lawyer may actually make your situation much worse. Even if you decide to plead guilty, you would be better off having a lawyer speak to sentence on your behalf. You should not guess what sorts of facts are important to courts in relation to the matter of sentence. You can not assume that the Crown prosecutor or judge will view your case leniently.
Indictable offences are more serious offences.
The possible penalties are higher than for summary offences, although you may still face imprisonment or heavy fines for many summary offences. Impaired driving, possession of narcotics, and most crimes of theft and mischief are hybrid or dual offences. A lawyer can best advise you as to what trial method is best for your situation. You must attend court personally at all times. If not, a warrant will be issued for your arrest.
