Well, I am not sure about the conclusion at this point but in order to move forward, here are some definitions I would propose using wiki’s definitions and current tread discussions:
Tag: highway=motorway to identify the highest-performance roads within a territory. Typically, these controlled-access highways have a minimum of two lanes in each direction that are separated by a barrier… Tag: highway=trunk for high performance roads that don't meet the requirement for motorway. In Canada, these roads must have some of the controlled-access features found on a motorway. Tag: highway=primary for major highway linking large towns … The traffic for both directions is usually not separated by a central barrier. In Canada, these roads usually have none of the controlled-access features found on trunk and motorway. Most of the confusion comes from the governmental pdf document, cited in the Canadian tagging guidelines (wiki), which uses definitions that do not correspond to those of OSM. Once most of us agree on a set of definitions, starting using the above, we should provide adjusted definitions in the wiki and remove the pdf document.

Similarly I live just off a road I would consider to be a tertiary level road. It runs for only 4 km and links up residential side streets, a high school, an elementary school and a small scale commercial zone. It is only two lanes wide but for over 50% of its length has a centre boulevard or a centre dual left turn lane. As well, less than 25% of its length has residences that off it and none where you can park on the road itself. Where it meets four main crossroads the intersections are as follows: Intersection A: full signal with priority given to the crossroad. Intersection B: a four-way stop. Intersection C: full signal with priority given to the road in question. Intersection D: a stop sign with the crossroad given full priority over the road in question. In addition there is a walking trail that crosses with a pedestrian activated signal but with an advanced warning signal as described at http://wiki.openstreetmap.org/wiki/Canada:British_Columbia#Highways_and_provincial_roads under "trunk". Driving the full length you would know it is a tertiary level route, yet I can take photographs of the route that could lead you to believe it is a trunk road. --- Another example is SW Marine Drive between Camosun Street and the University of British Columbia - https://www.openstreetmap.org/way/255865854#map=15/49.2428/-123.2196 . It is designed at the level described for trunk road at http://wiki.openstreetmap.org/wiki/Canada:British_Columbia#Highways_and_provincial_roads, yet the OSM contributors have designated it as secondary highway. I don't find this a "maddening" as you say, but then I feel we could adopt a more UK approach to the definition then a infrastructure/design POV.

It has to go from a town or city to another town or city. It predates or has lesser capacity than a motorway. It's one of these maddening "know one when I see one" definitions that makes perfect sense in the UK but is difficult elsewhere. Much of the Trans-Canada, f'rinstance, would be considered a trunk road.
