I've had some for a while, but no idea on the specs.
You should probably start with learning about term, whole/universal etc. types of life insurance. Not the best site per se, but I like the explanation here:

I'm no expert but I would suggest whole/universal. In a nutshell, term is like buying 20 years and then it expires. Whole/universal is until your death which makes more sense if you have kids and expect them to receive the funds.
For the one I got, I think I pay for 15-20 years or something and never pay another cent again. I think it was the performax gold from manulife, but not saying you have to go with that. I think I got the $100k one as I was not able to afford more when I first bought life insurance. I view it as a supplement to what I will leave behind, pay bills in the mean time etc. and not to cover everything as the link above says to do.
