A lawyer for Supt. David (Mark) Fenton will argue a reprimand is sufficient.
Complainants arrested during the summit weekend want Fenton fired.
The prosecutor says a year-long demotion would be enough to send a meaningful message.
The 27-year veteran of the force was found guilty last year for ordering indiscriminate arrests.
Retired justice John Hamilton is expected to sentence Fenton in about one month.
