Retailers in Fredericton can now set their own hours on Sundays.
City council passed a bylaw change on Monday night, which will allow store owners to decide when they will open and close.
Under the previous rules, they were limited to between noon and 5 p.m.
The change follows a request by the Retail Council of Canada in February.
One exception remains, however. Stores are not allowed to open at all on Easter Sunday.
Most New Brunswick municipalities limit potential Sunday openings from noon until 5 p.m.
Retailers in Fredericton have called on the city to update its Sunday shopping bylaw in the past.
Bathurst council scrapped its Sunday shopping bylaw in May and also gave stores the right to open when they want on Sundays.
