Gas prices jumped overnight in some cities across Canada, in many cases by around ten cents a litre, and by almost 20 cents in one city.

According to the CAAs gas price tracker, the price of gas is up nationally by just over three cents on average at $1.58 per litre, with some provinces seeing bigger jumps than others.

Kristine DArbelles, CAAs senior director of public affairs, said gas prices are being driven by a number of factors including international issues, seasonality, supply and demand and provincial taxes.

With hurricanes Fiona and Ian hitting coasts this week, delivery and supply of gas is likely affected for some markets, DArbelles said.

Storms can have an effect on gas prices, she said. Because where gas is coming from is slightly different across the country, that might mean that one province is feeling it a little bit more than another province.

In Alberta, provincially prices were up by six and a half cents, but up almost nine cents in Edmonton.

Meanwhile, Ontario prices averaged two cents more than on Wednesday, but in some specific cities it was a different story.

In Thunder Bay, gas prices were up by almost 20 cents, and in Peterborough prices were up 11 cents, compared with a gain of just around a penny in Toronto. In other Ontario cities, such as Brantford and Brockville, gas prices were up by four and half cents.

In Saskatchewan, prices were up almost six cents, while Manitobas prices saw just a one-cent rise. Quebecs prices barely moved overnight, while prices in British Columbia were up by almost four cents.

In some provinces, theres another jump in gas prices on the horizon as tax relief programs reach their limits.

Albertas temporary gas tax relief, introduced earlier this year when prices soared, is on its way out, albeit slowly. On Oct. 1, the province will reintroduce a tax of 4.5 cents per litre, still a far cry from the usual 13 cents.

Ontarios gas tax was cut to nine cents per litre from 14.7 cents effective July 1 and ending Dec. 31.
