Its completely up to you, your choice, goals, and aim. I know people who are driving trucks they make ok money - by reporting low taxable income-, normally take home 4-5 some time upto 6-7 per month. In early days, you have to drive on long haul such as toronto to calgary, with couple of years exp you might get job in town. The normal season is Mar or Apr to Dec. Many drivers normally don't work during winter period. Increase in income will be very slow, you may be earning same amount in 10 years if you don't buy your own vehicle.
There are lots of people who spent time and now are successful in their careers, I know people who are making b/w 100K -150K , some up to 250 in Investment and Medical (don't know exact figure) after 10 years of immigration. This includes IT professional, doctors, they did low survival jobs may be for couple of years then took lower paid professional jobs and after accumulating some experience they don't regret hard work. Where as, I know people who drive trucks majority is still making same what they were making in their early days little increase, expect some who took risk and started their own business, some people also left and started small business like pizza shops.
summing up, so its u r choice mate.
