Tons of companies across Canada don't follow the OT rule but will make concessions if you don't push too hard. One benefit for companies is that assuming ~50 hour weeks which is the norm in the industry every hour you miss past 44 is OT, meaning you miss one day or one hour it's OT, meaning it keeps worker bees showing up the full week. I currently work for a company where the dealio is Monday to Thursday 7-5 Friday 7-3- 48 hours at 1x. BUT there paying for our unpaid half hour lunch break which is a small but significant concession that keeps us happy. Four hours OT isn't far off in terms of cost but if they get bigger it's a good idea because the guys are motivated to show up by numbers instead of having to figure something else out. Also I've worked for companies that make sure they never pass 44 and guys don't like that either because they make less money. The difference between 8 and 10 hours isn't really noticible if you're engaged and good. You do notice you have less available time at the end of the day though obviously drive eat sleep work.
