After a two-year pandemic-prompted hiatus, the Dorchester Day Parade will journey up the avenue once again on Sun., June 5. The parade, which starts at 1 p.m. in Lower Mills, follows a three-mile course up Dorchester Avenue to Columbia Road.

The all-volunteer committee that organizes the event hopes it will quickly regain its foothold as the year’s largest celebration of Boston’s biggest and most diverse community.

It will be a tough task. There has been less outreach to local businesses than in pre-pandemic days since the committee has not sought to raise funds aggressively, according to panel chairperson Kelly Walsh, who says the parade’s coffers remain full after two years without spending.

The parade typically draws in participants ranging from high school marching bands and youth sports leagues to candidates for governor, along with a bevy of neighborhood civic organizations. Walsh says the committee is accepting applications through the end of the month from groups that would like to participate.
