Zippy, did provide a lot of good advice. There are others around here that could also probably give you some good advice but, as others said, this is not really the site for it. Many of the guys around here have already been down the marriage road and generally aren't that anxious to get back into it. and even the guys who haven't been married have taken a good look at it and concluded that it is much better to rent than to buy. If you want to start a REAL DISCUSSION, start one on the pros and cons of getting hitched vs. not.
But rather than try to talk you out of it, since you seem so set on the idea, I'll just throw out a few things to look out for. For more thorough and expert advice I suggest you check out the forum at

You think marrying a latina would be better than marrying a gringa and in some ways latinas probably do make better mates than gringas. However I think you'll find you'll be trading one set of problems for another (like D2864 suggested).
For example, latinas tend to be fiery and passionate. That can be a great thing in the sack, but can be a really bad thing after you've been married a while. Passion can manifest itself in other much less desirable ways such as anger, jealousy and suspicion. You said you don't like the head games that hot gringas make you go through, but latinas can be some of the biggest drama queens out there. I think it has something to do with their watching so many telenovellas though is probably just another symptom of that underlying tendency.
Another example is in some of the differences in values between latinas and what you're used to in Canada. You might not like the way gringas think but at least its something you're used to and understand. In Latin America, close families tend to be very important. this sounds like a good thing that we should emulate and maybe it is but you need to understand how that might manifest itself. When you marry a chica, usually you are really marrying her whole family much more than you'd be if you were marrying a chica. If a brother-in-law or cousin has a problem, that is also your problem and if that family has no money, it will probably be the rich gringo husband (namely you) that will be the first that they turn to to bail them out. Even when things are good, everything will revolve around the family. Expect to pay for several trips a year either for you back down there or for her family to come north to visit to placate your homesick wife and when they aren't visiting expect expensive international telephone bills.
You also mentioned not having to go through all the work and hassle involved with dating gringas, but you should expect a lot of work finding that foreign bride. Sure a lot of that work will be very enjoyable, but it can also be very expensive and there are a lot of potential pitfalls out there such as rip-off agencies and candidates who don't turn out to be what they say. Heck, there are even guys out there who post pictures of a pretty women who they then pretend to be and then after the hook is set work the mark over with RFM's. You'll probably have an extended correspondence before you make the trip to actually meet them. There are all sorts of scams. Just be very careful.
My last set of advice is to not lump all latinas together (like I've done above). There are differences between different groups but there are also exceptions to any rule. In GENERAL, ticas may not be your best choice for what you have in mind. Sure they're great for what we do and they can be very sweet. But other latinas sometimes see them very differently and as being somewhat snooty and superior. But the important thing for you is that, unlike chicas from most other latin countries, they're much less apt to be interested in relocating to the US and leaving their families, particularly the ones from the middle and upper classes. The reason is that their country is not the basket case that other countries are. Why would you want to leave paradise if all your family was there? Colombianas are a much better bet for you. Not only to they have wonderful personalities but they have every reason to leave their country regardless of their economic class - to escape all the violence if for nothing else.
Finally, even within a particular nationality there are important differences between chicas of different backgrounds and circumstance that you should not so eaily dismiss. You say you would not mind marrying a former MP girl, but in my experience there is something about working in the sex trade for any length of time that changes a girl. Once they learn how to use their pu*sy to manipulate a guy for money it changes their attitudes toward guys, towards themselves and towards the nature of the male-female relationship. Even if they're working class or poor girls who have never worked in the sex trade, the difference in your socio-economic background will always color your relationship. Like you said you always pay for it, one way or the other and that might be more true than you think. BTW, another aspect of international marriage is that regardless of the cultural differences, once you get them back to the US, unless you lock them in your house and keep them isolated due to language differences, they quickly pick up all the worst values of the gringas - materialism, control, community property.
Like Zippy said, the best way to do this if you really want to marry a latina is to find one who doesn't want to move back to the US and then keep her in her own culture.
