Looks like Murray wants to Twin highway 17 past Arnprior.. hopefully they mean as a 400 series highway rather than just twinning, but still some progress. could the 417 be coming to Renfrew soon?

I would think that it would end up looking something like Highway 11 north of Gravenhurst. That is to say, interchanges at major roads, but at-grade intersections at smaller side roads where building interchanges or access roads would not be worth the expense.
As the article mentions, work to extend 417 to Scheel Drive is underway right now. The next logical terminus is Renfrew, followed by Cobden (where a bypass would be required), then Pembroke. To Pembroke by the end of the decade may be a stretch, but that's what needs to happen for the Ottawa Valley.
