The City of Thunder Bay's new zoning by-law continues to be under construction. Administration provided an update to council on Monday night on the legislation in process. The new comprehensive zoning by-law offers simpler maps and less zones. The city has already held a number of public meetings on the proposed legislation. The comprehensive zoning by law was approved in principal last night and will be sent back to council at a later meeting. The document will also be posted on the city's website for public consultation for four weeks.
