RE: MAAC + Transportation
Again, this was an area that got left by the wayside for a number of years, but MAAC's admission onto the RABC (Radio advisory board of Canada) (Again, an initiative of Prez Bransfield) was an important step in monitoring frequency use.
The RABC kindof regulates frequency use, but my understanding is that it's more of an issue of co-operation within the members on that board. There is no "real" enforcement. (I stand to be corrected) There is some industrial use of our frequencies, but it is very limited and our's are apparently the "cleanest" frequencies out there, mostly because there are better options for industry.
That said, there has been some movement to use our frequencies, but some education from MAAC has been able to persuade in our favour. I recall one incident where it was discovered a large construction crane using related frequencies for some of it's operation. They weren't too happy to learn that some kid with a store-bought toy could potentially interfere with a rather important peice of their equipment.
As one vote on the RABC, we don't have massive influence, but we certainly keep up on any industry initiatives to head off any potential problems. The bottom line is there are apparently better choices for industry, but we need to be there to know what's happening.
