In Canada, EV car owners have experienced a lack of charging stations and lower than advertised battery life during our long winters. Is this true?

 Indeed, there is substance in the worries expressed by Canadian EV owners about the lack of charging stations and lower battery performance in winter:

Lack of Charging Stations: Canada still has a discrepancy in the number of charging stations in relation to the increasing number of electric vehicles notwithstanding efforts to extend the EV charging infrastructure. Although charging stations are becoming more common, their distribution, dependability, and speed might vary, which raises questions among EV owners particularly in distant or less populous places where the infrastructure of charging stations might be absent.

Winter Energy Performance: Battery Capacity Performance of EV batteries is highly influenced by winter. For numerous reasons, cold temperatures can shorten an EV's range by as much as 20% to 50%:

Lithium-ion batteries, often seen in electric vehicles, are less effective in colder climates. Reduced capacity and power output of the battery follow from slow down in the chemical reactions generating electricity.

EVs further deplete the battery by using energy from the battery to heat the cabin and the battery itself, therefore sustaining performance.

Cold can also affect charging times since the battery's capacity to absorb a charge is lowered and the battery management systems might restrict the charging pace to preserve the battery.

It's abundantly evident that:

Real-world experiences: EV users have experienced noticeably longer charging times and lower range under extreme cold; occasionally they have had to charge more frequently or have been stranded because of unanticipated range declines.

Infrastructure Problems: Some charging stations not operating at all or at least during severe cold spells have cast doubt on their dependability in very cold environments.
Better technology—such as more effective heating systems (e.g., heat pumps instead of resistive heaters) and better battery management systems to lessen the impact of winter on EVs—is under constant debate.

Considering these issues, even if the EV infrastructure in Canada is expanding and technology is developing, the existing situation still creates difficulties, especially in winter, which fits the experiences and worries expressed by EV owners on several platforms,
