The Canadian frearms safety course is a basic introductory-level safety course. It has nothing to do with law enforcement per se. So the training would be on how to handle a firearm safely, and it would be the same training given to any Canadian who wanted to acquire a firearm in Canada.
This was considered, at the time, to be a minimum level of training, so that customs officers would not be putting themselves or anyone else in any harm with seized firearms. They reported many situations in which they'd seized firearms that were found subsequently to be loaded, and unfortunately, without that level of training at the time, no one could unload the firearm safely. They simply didn't know how to handle it.
In fact, I was told about a situation in which someone had seized a firearm from an American trucker. It was loaded, and the only person who could unload the firearm was the trucker, who had been arrested and whose firearm had been seized. That was the only person who had the ability to unload the firearm.
So it was that basic level of safety training that they conducted in 1999. What you're describing would be a much higher level of training, and this would be in conjunction with the actual issuing of the firearms, which will be done in the future.
