The article implies Canada requires the charging to be billed by per unit time rather than per unit energy.<p>I'm not familiar enough with the ecosystem overall, but I can see an argument that time based billing would make more sense. If it's the equipment that's the bottleneck, a price structure that incentivizes customers to charge quickly could increase throughput.<p>The example in the article was something like the cost is low for 5 min charging and then goes way up. This could encourage people to grab just what they need and then charge at home overnight (for example).<p>I'd be interested to hear more of an argument about why it's actually bad (or good)
