Yes there is a national college which establishes standards, but the assessment of educational instutional programs and implementation of training standards is by the provincial college, following the enabling legislation which is by province. Similarly there is a federal act which establishes goals in health care, but the 'nuts and bolts' is at the provincial level.
I think there is consistency in training across the country in terms of the basic essentials of nursing such as standard precautions or skin care, but when you get into some of the more advanced skills like intubation or injection of medications there are legislated differences in the level of worker who is permitted to perform these skills. Also a lower level worker might be permitted to perform some skills if the agency policy says they can. For example, I believe the administration of oral medication by pca's is permitted only as per agency policy. In some provinces they might not be permitted to administer meds at all.
Handwashing is pretty basic, but there's a difference between a rinse with a shake, and a medical scrub. And I'm not sure that is adequately addressed with in-house training, which is fortunately going by the wayside.
Oh I better go on a walk. It is so sunny outside. Dora
