A new report says the Halifax Regional Municipality will have to hire eight additional bylaw officers to enforce new municipal cannabis rules.

If council decides to follow all of the staff recommendations, it would cost about $970,000 a year.

Once finalized, federal laws will let people grow four plants on their own residential property.

The HRM report cites concerns about the associated smell. They recommend only allowing plants to be grown inside the home.

They also recommend banning smoking cannabis on all municipal property and prohibiting private retail sales and cannabis-consumption venues.

The province plans to allow cannabis to be sold at some Nova Scotia Liquor Corporation stores. HRM planners are still working on amendments to regulate the locations of any facilities for producing cannabis.

"Typically, they're located in industrial or business-park settings," said Jacques Dube, HRM's chief administrative officer. "It's a question of a zoning bylaw."

Proposed fines will offset some of the costs. HRM staff recommend fines ranging from $25 to $2,000 for breaking the smoking rules and from $1,000 to $10,000 for growing cannabis outdoors.

Councillors will debate the report Tuesday. Cannabis will likely be legalized by September.
