About the Network

BestBidz is Ontario’s Construction Association Network – the product of a collaboration between 12 Local Construction Associations (LCAs) across the province of Ontario. BestBidz has been formed with the goal of enhancing communication between the buyers and sellers of construction in Ontario by providing a state-of-the-art online marketplace to facilitate tendering.  Click here to access the Electronic Plan Room.

BestBidz On Demand

Ontario’s Local Construction Associations have recently introduced a new Invitation to Bid software for General Contractors (and other contractors that sub out work), known as BestBidz On Demand. This software has the ability to replace many programs and processes you may be employing currently to manage your subcontractor database, distribute plans & specs (like FTP), send out bid invitations, and track responses from subs, making the process much more efficient for your company. To learn more about this innovative software, click here.

The LCAs that comprise BestBidz are non-profit organizations that have been serving the industry for decades, some as early as 1867! These member-supported mixed-trade organizations are committed to providing services in the areas of advocacy, relationship building, standard practices, construction documents and seals, commissioner of oaths, education, training, communications, and social networking.

BestBidz has also formed an unprecedented strategic alliance with Construction Market Data (CMD), Canada’s leading provider of nation-wide construction project data, plans & specifications, news, analytics and forecasts. As an added benefit of this alliance, members of BestBidz Member LCAs get Exclusive Discounts on CMD Products (some conditions and exceptions apply – click link for details)
