This paper discusses hours of rest for Canadian shipping employees on
the basis of statutory regulations, the research literature and consul
tations with representatives of the shipping industry during four work
shops held in different parts of Canada. Topics include analyses of cu
rrent regulations, operational practices and research on work and rest
and on rime of day and rest, and recommendations for change. The anal
yses found that current regulations do not distinguish between sleep a
nd recreation during rest periods and fail to take into account time o
f day effects in relation to quality of sleep. The proposed changes in
the regulations require the use of non-rotating 24-hour duty schedule
s providing for minimum rest periods and maximum work periods.
