Ontario's newest provincial holiday is coming up this Monday.

While many people are making plans for Family Day, many retailers are frustrated about how the new holiday will affect business.

"I think the province has certainly dropped the ball in terms of how they've implemented Family Day," said Cindy Vanbuskirk, General Manager of Ottawa's Rideau Centre.

Although many stores are traditionally allowed to open on statutory holidays, city permits don't cover the new holiday. That means many stores will be forced to keep their doors closed.

"We are absolutely not allowed to open on that day," Vanbuskirk told CTV News. "I'm trying not to put a dollar value on the lost business, but it is certainly substantial."

A spokesperson from Ottawa bylaw services says businesses simply didn't have enough time to submit applications that would have allowed them to stay open.

"Because of the time frame that the family day was proclaimed by the province, there would not have been enough time for the businesses to make applications for us to process them," said Christine Hartig of bylaw services.

The rules get especially complicated for those operating two businesses out of the same location.

In Augusta Township, retailer Marie Riopelle operates a postal outlet and LCBO agency out of the same convenience store but is only allowed to open her postal shop.

"Seeing I have to open, it would've been nice if I could have sold alcohol," said Riopelle.

For those looking to do some shopping, Sparks Street will be the only tourist zone fully opened in Ottawa.

Police say store owners who ignore the rules and open their doors to customers could face stiff fines.

"We're only going to be acting based on complaints. If we receive a complaint, we'll initiate an investigation," said Ottawa police Const. J.P. Vincelette.
