The Ontario Federation of Labour plans to hold rallies in 20 Ontario cities, including Windsor, on Sunday, International Workers' Day.
The federation of labour unions has a list of demands for provincial party leaders as they head out on their election campaigns.
On the list of demands, a $20 minimum wage, permanent paid sick days, affordable housing, and the repeal of Bill 124, which froze pay increases for public servants to one per cent a year.
The other issues are less specific and include climate justice, an end to racism and oppression, and decent work.
In Windsor, the rally starts at 1 p.m. at Charles Clark Square downtown and should wrap up by 3 p.m.
The federation said after four years of what it calls attacks on workers and two years of a pandemic that revealed deep cracks in public services, it is time for provincial party leaders to act.
More than a dozen "issue-specific feeder marches" will culminate at Queen's Park in Toronto for a rally.
