In 1925 each day of the OHW celebration had a theme.
- Monday – ‘Civic Day’ – granting of the city’s charter after the pageant parade, sports
- Tuesday – ‘Soldiers’ Day’ – parade of the Returned Soldier, sports, regatta
- Wednesday – ‘New Ontario Day’ – pageant parade, sports
- Thursday – ‘Children’s Day’ – children’s sports tournaments and fireworks
- Friday – ‘Pioneer Day’ – old-timers sports, horse racing
- Saturday – ‘Railroad Day’ – open house at the railyards, sports, and fireworks
A six-page “Official Programme” with the complete details on every event was printed once all of these were finalized. There were parades, sports, and dancing every day as well as many special events.
In 1935, each day of OHW was sponsored by one or more community organization and the days of the program were named for their sponsors.
- Sunday and Monday – 159th Battalion Reunion Days
- Tuesday – Motor Club Day
- Wednesday – French Canadian Day (Cercle Canadien Français, Fédération des Femmes Canadiennes-Françaises (FFCF)
- Thursday – Knights of Columbus Day
- Friday – Shriners Day
- Saturday – Associated Canadian Travellers Day
The Motor Club put the emphasis on swimming and water sports. The Knights of Columbus prepared a program that was much like Children’s Day in 1925. French-Canadian day was like a Saint-Jean-Baptiste Day celebration and differed from any of the days in 1925 in that sourrounding communities were invited to join in the celebrations. The unveiling of a monument to Jacques Cartier at McMurchy Park was the highlight of the day and warranted attention in the Globe. Sports and parades were featured every day.
The 1935 program was published in the Nugget.
French Canadian Day activities were printed in their program.
