It might be helpful to get a bit more info.
I noticed you are spending Canadian dollars, so I assume you are in Canada. Where in Canada? Depending on where you are, $2000 can go much farther, depending on what you want and where you shop.
How many are in the band? What sort of music are you playing? What sort of gigs are you playing? The answers to those questions might determine whether you need a 15" speaker system, or something bigger or something smaller, how many channels of mix you require, how loud it needs to be. It could determine whether it's even worth buying a PA. In many cases, it might be better to rent what you need. If the venues are really big, you might determine it's not worthwhile to buy a system for the gigs, but a considerably smaller system for Practise. The smaller system could require less money, and that money you could invest in good quality microphones or some other asset which can put your mind at rest when you are renting.
Do you have a "sound tech"? If not, you might consider going with a powered mixer, which will use far less space regarding transport and in the house, but then makes it very uncomfortable for a "sound tech" to use, due to the way the system plugs in.
There are several ways you can go, and more info would give people a better idea of advice for you. Remember, the advice is free, and worth every penny.
