Const. Wynn died on Wednesday morning, four days after he was shot in the head during a routine licence plate check at the Apex Casino northwest of Edmonton.
Officials expect thousands to attend the regimental service, which will begin at 2 p.m. CT.
A funeral procession originally planned to start at 1 p.m. on Monday has been shifted one hour earlier to noon to ensure there is time for a full procession prior to the funeral.
CBCNews.ca will be live streaming from the procession and funeral, beginning at 1:30 p.m. MT.
A second officer, Aux. Const. Derek Bond, was also shot and is recovering at home.
His family issued a statement through the RCMP on Friday expressing sympathy to the Wynn family and thanking the public for their messages of support.
“Derek's recovery is progressing, but this remains a very difficult time for us,” the family wrote.Suggest a correction
