Both. There are max 50 weeks of EI paid - biological mothers get 15 weeks of pay, then the remaining 35 weeks of the pay in the first parental year is shared between parents (even for adoptions). So, Mom & Dad could both take 15 weeks off (15 x 2), and Mom or Dad takes the remaining 20 off. There are many combinations. Of course, EI only pays $50k a year max, so many employers will offer benefits packages that match 75-80% of your salary for up to 16 weeks (maternal and/or paternal leave).
