A surge in prices at the pumps across Canada -- including an average of $1.37 per litre price tag in Vancouver -- has led frustrated drivers to call for a gas boycott.

More than a million people have joined the "Don't buy gas on April 15th" group on Facebook as cities across North America deal with yet another surge in prices ahead of the weekend.

Vancouverites are seeing the country's highest average gas prices, while Montreal ($1.35), and Halifax ($1.33) rate second and third.

Here's a look at Canada's ten most expensive places to buy gas (according to GasBuddy.com):

• Vancouver: $1.37
• Montreal: $1.36
• Halifax: $1.33
• Quebec City: $1.32
• Toronto: $1.32
• Hamilton: $1.31
• Kitchener-Waterloo: $1.30
• London: $1.30
• Barrie: $1.29
• Victoria: $1.29

In Toronto, the average price per litre skyrocketed to $1.32 on Friday morning, the highest the city has seen in three years. The hike was 3.4 cents higher than Thursday's average price, leading to lineups at the pumps as drivers hurried to fill their tanks before the hike took effect at midnight.

One year ago, before rising oil prices and the province's implementation of the harmonized sales tax, motorists in Toronto were paying $1.00 for a litre of regular gasoline.

The good news for Torontonians desperate for an affordable pre-weekend fill-up is that a handful of gas stations are still charging in the low $1.20 range, according to TorontoGasPrices.com, which monitors stations throughout the area.

Canada's national average price was just above $1.28 per litre on Friday, with the lowest prices found in Alberta (just under $1.18 in some areas), and the highest in Newfoundland, at more than $1.38.

While gas prices are still much cheaper in the United States, they have risen there for 24 days in a row, and are now above US$4 per gallon (about CAN$1.02 per litre). The prices mirror those of the summer of 2008, just before the world economic crash hit the U.S. with particular ferocity.

Analysts attribute the recent gas price spike to higher oil prices, which have been affected by the conflict in Libya. Crude prices have risen 28 per cent the uprising there began in mid-February.

Energy consultant Mike Ervin says there is a much stronger demand for gasoline now than there was in 2008, but believes prices have peaked for the next while.
