Don't be so sure of that. Employers have the right to "temporary layoffs" up to 13 weeks in any 20 week period, or up to 35 weeks in any 52 week period. If an employee receives EI, the counter stops. If the employee receives legit company paid insurance benefits the counter stops.
The case noted in that article is unique -- the fellow laid off was off for more then the allowed 13 weeks AND he did not enroll for EI. Not many people are in a position to operate under those terms.
Most biz owners are pretty savvy when it comes to employment laws. If a laid off employee is coached by a lawyer and has deep enough pockets to survive without EI for 13 weeks, then gambles their employer won't call him back before the 13 week limit, he'll be pushing a string in court.
