Thunder Bay Mayor Keith Hobbs attended a meeting of the Northern Ontario Large Urban Mayors and Chief Administrative Officers last week where the plan was the topic of discussion.
The leaders say they're looking forward to what the plan may offer the region but are concerned about how long it's taking to get it in place.
The mayors also added the plan should ideally include new sources of funding to help spur growth.
The group is looking to meet with Northern Development Minister Michael Gravelle and Infrastructure Minister Bob Chiarelli to discuss the plan.
