Manitoba Progressive Conservatives are promising to allow grocery stores to be open on Sundays and statutory holidays if they are re-elected in September.
Leader Brian Pallister said Manitobans deserved the flexibility to buy groceries when they wanted.
Earlier this year, the owner of an independent chain of Winnipeg grocery stores criticized the law which requires store to close after he received a $10,000 fine for opening on a holiday.
Pallister called the law outdated and unnecessary.
However, he said any change to the law would not impact the requirement to keep stores closed during specific hours on Remembrance Day.
Manitobans go to the polls on Sept. 10.
