R. v. Rawn, 2012 ONCA 487 is a useful sentencing case for dangerous driving matters:
 General deterrence and denunciation are the most important factors in the determination of a sentence in a case such as this one: see R. v. Nusrat, 2009 ONCA 31, 244 O.A.C. 241. Other, like-minded people need to know that irresponsible use of a motor vehicle on our highways will not be countenanced. A sentence can only denounce conduct and deter others to the extent that it is punitive. The essence of general deterrence, is, therefore, punishment: R. v. B.W.P., 2006 SCC 27,  1 S.C.R. 941, at paras. 2-5.
