"canonical" is a term often used by theorists. Almost always theorists are interested in capturing the essentials of a phenomenon. That means they restrict their investigations to model Hamiltonians, which have the bare minimum complications to show typical spinglass phenomena such as aging and non-exponential relaxation. In this sense canonical can be translated into "as simple as possible but as complicated as necessary". An example would be an Ising Hamiltonian where nearest neighbor interactions follow a certain distribution which contains competing interaction (meaning ferromagnetic and antiferromagnetic interaction) and some element of randomness. If the distribution of the exchange interactions is Gaussian, this model is known as the Edwards–Anderson model. This is pretty much the simplest problem one can consider to get spinglass properties. Still it is a very complicated problem to solve.

Christian, I like your style of explanation. I am sure you teach very well!!

Thank you so much.

If I may expand the question and bring the subject down to numbers. In my understanding "canonical"  refers to frustrated magnetic systems which share similar characteristics with  the archetypal spin glass systems like CuMn, AuMn. According to Mydosh, the spin flip  time τo is at the range of 10-9
