Can You Drive Another Car During the Interlock Program?
The short answer is no, and it matters most on a road test. What the "I" condition permits, what it costs to ignore, and who else can be charged for it.
Ontario approves two providers, and you sign a lease with one of them before you can be reinstated. Here is what each publishes, and what they do not.

Ontario’s ignition interlock programme runs through Smart Start Canada and ALCOLOCK Canada. A signed lease agreement with one of them is one of only two components in a reduced-suspension application — the other being the Back on Track assessment. Reduced suspension Stream A, Stream B and Stream D in Ontario covers that application in full.
We have no commercial relationship with either. We do not install devices and we are not paid to recommend one.
Smart Start Ontario publishes a fee schedule. As at 27 July 2026 it listed a monthly lease of $77.97 including tax, an MTO monthly fee of $7.50, installation and removal at no charge, an unlock code at $84.75, a violation reset at $96.05, a missed appointment at $113.00 and early termination at $282.50.
ALCOLOCK Canada does not publish an Ontario fee schedule. It does publish a location list, which includes an Ottawa service centre at 5340 Canotek Road, a Nepean centre at 151 Bentley Avenue, plus Carleton Place and Cornwall.
Treat the Smart Start figures as one provider’s published price on one date, not as “the Ontario price”. Get your own quote from both.
Not the handset. Where you have to drive every 60 days. Ontario requires you to return to your provider every 60 days so the device can be downloaded and calibrated, and a missed appointment is a programme violation — the same category as tampering, carrying a six-month extension for a first offence.
Over a twelve-month condition that is six trips. A service centre twenty minutes away and one an hour away are very different propositions in an Ottawa February.
That last one matters more since the 2026 Ontario interlock rules changed, because a first-time condition can now end at nine months rather than twelve.
Ask both providers directly before signing. Removal and reinstallation may be treated as an unauthorised de-installation if it is not arranged properly, and that removes you from the reduced-suspension programme entirely.
No. Only the approved providers may lease, install, calibrate or remove a device. We are an independent driving school: we teach the device and rent an interlock-equipped car for road tests.
The short answer is no, and it matters most on a road test. What the "I" condition permits, what it costs to ignore, and who else can be charged for it.
We rent an interlock-equipped car for a G2 or G road test and teach the device in ten hours of in-car training. Send the date and we will quote it in writing.
Phone is faster. Someone answers Monday to Saturday, evenings included.
