Here in Ontario Canada I believe refusal to blow is automatically considered the same as blowing over plus maybe an additional fine too?.
Our first offence gets a one year suspension plus a subsequent year of driving a 'blowmobile'...your car w/ an approximate $3000.00 blow monitor ignition-disabler device, rental/installation/maintenance at your cost..
The only way around the 'blowmobile' thing is running the two full years without driving or you can motorbike for the second year being there's no blow machines for bikes yet?.
Snowmobiling/4 Wheeling on our Provincial trail systems is well monitored by the Police and considered the same as being on the roads here so you can lose your licence or be nabbed running under suspension on a weekend w/ the boys!.
