The 2019 Employment Insurance (EI) Premium rate will be going down in 2018. The rate will be decreasing from $1.66 to $1.62 for every $100 of insurable earnings. This will be the lowest EI premium rate since 1980. The 
decrease in the effective rate for employers will be slightly greater, as employers pay 1.4 times the amounts paid by employees.
Nonetheless, total premium deductions will actually be increasing in the coming year, due to an increase in Maximum Insurable Earnings, from $51,700 in 2018 to $53,100 in 2019.
As a result, the maximum employee deduction will be increasing slightly to $860, and the maximum employer contribution will be rising to $1,204.
If an employee has net income over $66,375 in 2019, and they have received EI premiums for more that one week in the prior 10 years, they will have to pay back a portion of their EI premiums. This clawback rate will be 30% of the amount that their net income exceeds $66,375.
