I don't understand this urge for a "connected network" of bicycle lanes. As a cyclist in York Region, I can certainly say first hand that bicycles can ride safely and comfortably on streets without any cycling facilities. It's unreasonable to expect that all streets have bike lanes, so most trips inevitably have some mixed traffic portions anyway. Cyclists go from everywhere to just about everywhere else, and I think lanes should be focused where there is high cycling demand (such as Queens Quay for example) or where road layout is unsafe or unpleasant for cyclists (such as long bridges, underpasses or arterial roads).
Bike paths are also useful for adding shortcuts, a function they fulfill perfectly even when not connected to any other bike facilities. Thanks to mixed-use trails, my commute is 1.4km shorter by bicycle than it is by car.
That said I do understand the need to fill missing gaps in bike paths because it is often awkward to transition between path and street riding.
So in short, a lack of "network connectivity" isn't really an argument against building paths and lanes because cyclists already cycle in mixed traffic anyway, and will benefit from bike lanes even if they don't connect to any other ones.
