How about this list? Gaps are in kilomet(er|re)s. I don't have all Canadian Highways. Some here are national, some are provincial.
There is a "National Highway" network which are considered strategic, but they are numbered provincially, aside from the TCHs.. I "connect" some like BC-3/AB-3. These are all the gaps greater than or equal to 160.9km.
In case anyone is wondering how those two places in Ontario have a big gap, when they're both on the TCH it's because ON-11 is a northern loop.
Oh, and Levis, QC to Riviere-du-Loup, QC appears twice because I have them listed under both QC-20 and the TCH.
