Scott asked a very good question in the comment section of my last post, and since I'm getting a few more readers who aren't Canadian, family or close friends, I think I should explain my qualification a bit.
I am an Advanced Medical First Responder in the Canadian system, which is comparable to EMT-B in the American System. The next level of training for me would be Primary Care Paramedic, a 2-year college degree, which I believe is similar to EMT-I. Then comes Advanced Care Paramedic, or EMT-P. That is my understanding of the system, but then we have Critical Care Paramedics too...not sure what they would be considered in the States.
I think the main difference between AMFR (usually just called MFR) and EMT-B is that we cannot transport patients on a normal basis. We are only allowed to transport if the roads are closed, (like during a marathon) or there is a state of emergency. Our trucks are fully stocked to BLS standards in case we get called out though, we are to be ready at all times. Barring disaster, we are usually just first response units at major events. Having us there cuts down on a lot of needless 911 calls, as we usually treat and release without any need for activating the next level of care. This means we get a high volume of not-so-bad calls, and very few crazy ones. I rather like this at the moment, I'm creating a solid knowledge base, getting more and more comfortable with the simple calls and basic skills. After I finish my degree I may move onwards and upwards to Paramedic, but we shall see. For now, I'm happy where I am.
