FAQ011: Are there differences in how long a driver may operate in a single duty period in Canada and the United States?

Answer: In the United States, for drivers of property no driving may be done after 14-consecutive hours until the driver first takes 10 consecutive hours off duty.  (393.3(a)(2)).  For drivers of passengers in the United States, no driving may be done after being on duty 15-hours following 8 consecutive hours off duty. (49 CFR § 395.5(a)(2))

Yes. In Canada, no driving may be done after 16 hours have elapsed beginning with the first on-duty activity after the conclusion of an 8 or more-consecutive hour rest period.  (SOR/2005-313 – Section 13: Mandatory Off-duty Time)
