Need some help deciding!

Been with my current carrier [small fleet] first company and only company I've ever worked for 9 years as an independent contractor. Steady work but no growth.
Got offers to road test with Midland, Kriska, and Transx
I’ve driven all over Canada and into the US. I am long hauler, so the jobs offered all are OTR.

For those who switched after years with one company — what made you decide to leave, and what did you look at first (pay, freight, equipment, dispatch)? I have been told that because of today's economy, work has been slow, but the company I drive for has been consistent with pay and with work. I am from Toronto if that helps. Any advice or support would be appreciated ! Thanks gentlemen.

[ started off with 28 cents and I am currently getting 30 cents a mile running team. I have asked for a raise but they declined. I get about 15k to 20k miles per month. Take home pay could be $6k to 8k [CAD] a month BEFORE taxes]

To be honest I have learned a lot in this company. When I first started out I made multiple mistakes and the company has stuck with me thru thick and thin. I have managed to keep a clean CVOR if that helps.. ]

 

I am an independent contractor. I get paid hst on top of my pay.

 

Tax that the company doesn't cut. I think its different out here in ontario then in the states. The company doesn't cut tax, they include the hst into my pay. I have a accountant that prepares the numbers for me either quarterly/annually. I know this forums is predominantly usa based
