To my knowledge, the only jurisdiction to actually do so is Ontario. Ontario spent a lot of time discussing conditions to make it happen. It's a matter of deciding if a suspension without salary can happen from the very beginning, or when a certain threshold is reached, or if taxpayers will have to collect the salary payments made during the process.
Disciplinary procedures can take several years. However, it seems to me that nothing encourages people to behave better when they know that, even if their behaviour is grossly inappropriate, they will still get their salary for years at a time. So, it's a difficult topic, but currently, I think the Royal Canadian Mounted Police Act does not reinforce trust from the general public.
