The rules were changed in 1996, as I mentioned, and they became much stricter in terms of qualifying. First of all, you have to have a certain number of hours worked in the previous 52 weeks to qualify for benefits. And when the rules were changed, the number of hours worked doubled, and in some cases tripled, so that many people don't have the requisite number of hours.
Secondly, if you leave your job for certain reasons that under the act are not considered just cause, you're penalized and you can't get benefits.
Thirdly, whether or not you get benefits depends on the unemployment rate where you live, whether you've worked during the previous two years, and so on. It's a very complicated system. But you could have a woman, let's say, who's been in paid employment for years and then suddenly drops out and has a child. She might be out for a couple of years and try to get back in. She's then considered a re-entrant and she has to work something like 900 hours.
