Governments need to pass laws and regulations preventing building owners, condo associations etc. from hampering the installation of electric chargers in parking garages. Yes there is a cost, there might be a need to bring some stuff up to standards (which should be done anyway) but saying "rules forbid you to have a charger in the garage" should simply be made illegal.
If there is a safety issue due to the antiquated electrical grid then there is a safety issue and that cannot be changed unless the infrastructure is updated, which for a building my size could easily run into the hundreds of thousands of dollars. Who's going to pay for that? The renters? Most of them are literally a pay cheque away from being on the street and they simply cannot sustain a major rent increase to cover those costs. Landlords and developers aren't going to pay for it, at least not if they can't recoup those costs.
The infrastructure in the building might not even be the problem, it might the public electrical infrastructure in the surrounding neighbourhood that needs to be upgraded. Who's going to pay for that? The taxpayer? The public is already maxed out with taxes upon taxes upon taxes.
Then it gets even more complicated, strata/condo bylaws are a City's jurisdiction, not the Provincial Government and not the Federal Government, so coming up with a policy that applies to all strata's, condos in a Province or in Canada as a whole, cannot be easily done - it has to be done on a city by city basis.
The other problem with mandates is that, I don't know if you've been paying attention over the last couple of years, but things tend to get a little violent when Governments start interfering with peoples lives, especially when those interferences are based on "science".
