The biggest immediate threat to Canada’s ability to emerge from the COVID crisis with a functioning economy lies not in who gets which type of vaccine, how quickly the provinces wean themselves off shutdowns or how many extra billions the Liberals are determined to spend in search of popularity.
It lies in a pipeline. Not the better-known Keystone or Trans Mountain lines that have been the focus of intense national and cross-border debate, but the more obscure Line 5, an Enbridge conduit that carries petroleum and other products from Western Canada to the eastern provinces by way of Michigan.
It usually gets little attention because it’s been in operation with minimal drama since the 1950s. Its future has suddenly become questionable because Michigan Gov. Gretchen Whitmer, a close ally of President Joe Biden, wants it shut down.
