So if im going to buy a vhf radio and only staying in canadian waters what do i need? And where can i get it?
Easy, you need 2 things, one for safety and the other to operate the radio lawfully.
1. To take full advantage of the safety features offered by Digital Selective Calling, get an MMSI (Maritime Mobile Service Identity) number that you program into your VHF radio. They are free and you apply to get one through Industry Canada. Here is a link that explains how to apply:

The MMSI is a valuable safety feature because it provides search and rescue officials with detailed information about you and your vessel, so that if you press the red button and send out a DSC distress call, this information will be instantly available to the authorities, which will make it easier to locate you. If your radio is connected to a GPS/chartplotter, this distress signal will also provide your precise GPS coordinates, which is even more important for locating you in an emergency. Finally, it allows you to call others (who have MMSI's) in a very automated way without hailing them on channel 16, but I don't believe many people take advantage of that feature.
2. To operate the VHF lawfully, you need the ROC-M, which is the operator's license. It is good for life. Courses are offered though Power Squadrons and others. I got the materials from Bruce Stott who operates the Gulf Islands Cruising School, studied on my own and he administered the exam. So there are a number of ways to go about it; they all cost money, but very little compared to what gets spent on boating. Not a difficult exam, but it requires some time and preparation. It is very helpful in that it fully explains all operating protocols and rules, the phonetic alphabet, and the safety features of DSC and MMSI.
If someone spends a lot of time on the water, I do not understand why they would not get the license, an MMSI number, and connect their VHF to a GPS. VHF and its proper use are vital to safety on the water.
