R v Capobianco

R. v. Capobianco

2010 ONCA 589
Court of Appeal for Ontario — MacPherson, Rouleau and Karakatsanis JJ.A. | September 13, 2010

Background

Franco Capobianco was driving from westbound Rutherford Road onto northbound Highway 400 when he drove through what's called a "bull-nose" — two solid white lines that start at a point and travel back towards the on-ramp, essentially marking where the highway shoulder meets the on-ramp shoulder. He was charged and convicted under section 154(1)(a) of the Highway Traffic Act for "failing to drive in a marked lane."

On appeal, the summary conviction appeal judge allowed Capobianco's appeal and entered an acquittal, finding there was no evidence that his manoeuvre wasn't made safely. The Regional Municipality of York wasn't satisfied with that result and appealed to the Court of Appeal for Ontario, raising fundamental questions about how the law should be interpreted.

Issues

1. Does section 154(1)(a) of the Highway Traffic Act contain one offence or two separate offences?
2. If the section creates two offences, is driving through a "bull-nose" an offence under section 154(1)(a)?

The "And" Problem

Section 154(1)(a) requires that "a vehicle shall be driven as nearly as may be practicable entirely within a single lane and shall not be moved from the lane until the driver has first ascertained the movement can be made with safety." The Crown argued this creates two separate offences: (1) not staying in your lane, and (2) changing lanes without checking if it's safe. Under this interpretation, you could be convicted just for leaving your lane, even if you did so safely.

The Court of Appeal disagreed, and their reasoning was brilliant in its simplicity. While the English version might seem ambiguous because of that word "and," the French version of the same law is crystal clear. The French text doesn't use "and" at all — it says a vehicle must stay in its lane "without leaving it until the driver has assured himself that such a manoeuvre can be executed safely." There's only one obligation, not two.

The court applied the principle from R. v. Daoust: when one official language version is ambiguous but the other is clear, you go with the clear version. That interpretation reflects Parliament's actual intention.

Key Takeaway

Section 154(1)(a) creates only one offence, and the Crown must prove both that you left your lane AND that you didn't check if it was safe to do so.

This is huge for defendants — it means you can't be convicted under this section just for momentarily drifting out of your lane if there's no evidence you failed to check for safety first. Both elements must be proven beyond a reasonable doubt.
