Urgent: Master8 and other friends on I-94

Parents need to land in Canada soon. They arrived US first, and we'll drive them to Canada for landing purpose. Questions:

-Do they need to surrender their I-94 (they may stay overnight in Canada)

-Any issue when they return to U.S.

-When they arrived U.S, custom only admitted 40 days for their stay in US. Does it cause any issue when they return to US from Canada (wihin I-94 expiration date).

thanks a lot
