The Manitoba government is willing to double its funding for a major expansion of CentrePort Canada in northwest Winnipeg to prevent it from being held up by a lack of federal cash. An estimated $60 million is required for water and sewer infrastructure to support the first phase of the inland shipping port's expansion project, CentrePort South. The province and City of Winnipeg previously committed $20 million each, conditional to a matching amount from Ottawa. But that hasn't come through "despite extensive provincial engagement," Premier Heather Stefanson said Friday.
