I'm unaware of any intention by the CRA to eliminate the leads program. As I've indicated, the new program only relates to more significant tax non-compliance and taxes in excess of $100,000 that have an international component. Those are not limitations under the leads program.
Under the leads program, my understanding is that somewhere in the order of around 10% of the leads provided actually result in assessments. The hope is that by having a more rigorous relationship with the informant, it will increase the number of assessments that result.
