The next day, a fire call on the Grand Rapids First Nation pulled a number of workers away from the strike.
Workers also responded to a call in Churchill, Man., after the hospital in that community lost power.
Manitoba Hydro management and the union have a provision in place to provide emergency services during the strike.
Picket lines will continue to encircle Manitoba Hydro Place in downtown Winnipeg on October 4, the second full day of the strike. October 5 is the first day of missed wages for members of the International Brotherhood of Electrical Workers.
Spirits and support for the strike remained high on the picket line, but some workers expressed hopes a resolution will be reached soon.
"We hope [it's] not too long," Gena Dondo said. "I don't know if we can go too long without getting paid for over a week."
Management for the Crown corporation said customers may experience disruptions or delays in services such as power restoration after weather-related outages, electrical inspections, and power connections to new subdivisions.
Manitoba Hydro also said management is working to maintain essential services.
