Transportation Association of Canada (TAC)

TAC is a non-profit association of government and industry members which acts as a neutral forum for the discussion of transportation issues and as a centre for technical excellence in surface transportation infrastructure.

Two members of the Highway 416 - Veterans Memorial Highway staff were given the opportunity to present seminars at the 1998 Annual TAC Conference on what they discovered and accomplished during their work on the Highway 416 Project. To view their papers, click on the following links:
