Unfortunately, within big cities there is no such classification scheme with numbers. So you have to judge how the street looks like.
Tertiary roads usually have painted lines, no reduced speed, right-of-way, traffic lights, and bus routes.
Residential roads usually have no painted lines, reduced speed limits, stop signs, crossings without signs, no traffic lights, and no public transport.
However, you will hardly find all five properties at once, so you have to decide how to map a street that has just two or three distinguished properties.

In Britain, a tertiary road is between a B road (secondary) and unclassified. Residential is a unclassified road with houses on it.
I don't know how this fits in over there.

You are from Canada, right? So you should look at
http://en.wikipedia.org/wiki/Provincial_highways_in_Ontario
In Ontario, there is a list of primary, secondary and tertiary highways.
Secondary (number above 500) and tertiary highways (number above 800) are mainly located in Northern Ontario - if you want to map there.
Furthermore, tertiary is a perfect classification for former highways:

Did you find the roads you have searched for?
