Montreal is 10 hours behind Islamabad
There is no standard 8-to-6 overlap. Someone joins early or late.
Islamabad and Montreal are too far apart in time (10 hours) for their workdays to line up during regular hours. For anything urgent, agree on an early-morning or late-night bridge hour in advance so nobody's caught off guard. Watch the DST gap — when Montreal changes its clocks and Islamabad stays the same, this window slides by an hour.
