Yes. Generally speaking, the summary conviction offences carry a maximum penalty of only six months' imprisonment. In some other cases, it's 18 months, but as a maximum. That's one of the major differences. It also just generally represents a less serious offence when the crown elects to proceed by way of summary conviction. That might be a way to include greater latitude in the Criminal Code.
