Absolutely not. The penalty for a refusal is the same as if you blew over. The difference is the evidence that is required to prove the charges.
With a refusal, it need only be proven that he officer had the grounds to make the demand and that you refused to comply with the lawful demand as the Criminal Code requires. This is relatively easy to prove and therefore, most often results in a conviction.
However, if you blow and you blow over, this is not the end of it, as so many things have to be in order for the charge to actually be proven in court. Impaired driving and Over 80 charges are so technical nowadays, that they frequently result in findings of Not Guilty where things have been done incorrectly.
The issue is that these offences are highly technical and require extensive documentation, testing, and other factors and as such, if even the slightest thing is missed, the charge could then fail in court and the accused is off the hook. There aren't really any technical issues with a refusal.
Please let me know if you require anything further at all as I am happy to chat further.
