With more snowy weather blasting some of the country's largest airport hubs, getting home for Christmas might only be a dream for some Canadians.

Pearson International Airport in Toronto and the Vancouver airport were both reporting delays Wednesday morning as travellers continued to try to reach their holiday destinations.

"As people try to get home for the holidays, it is going to be one of those very tough going days," said CBC reporter Colleen Jones.

Several storms have battered much of Canada over the last week, setting the country up to see its first coast-to-coast white Christmas since 1971.

Environment Canada has issued weather watches, warnings and bulletins for most of Ontario on Wednesday.

Toronto received another 20 centimetres of snow on Wednesday morning. The forecast from Environment Canada indicated the snow would turn into freezing rain later in the day.

In Vancouver, about 20 centimetres of snow was also expected to fall by Wednesday.

Flights cancelled

British Columbia has already been pounded by one of the snowiest Decembers it has on record. A storm earlier in the week had already dumped up to 70 centimetres onto B.C.'s southern coast.

Havoc was wreaked on many Canadians' departure plans when more than 300 flights were cancelled at Pearson International Airport in Toronto after a snowstorm swept through the region Friday. It caused flight cancellations and significant delays across the country.

The airlines there said they're adding more planes to deal with the backlog, but the delays could take days to clear up.

Many travellers have found themselves stranded at airports and waiting hours or even days to get onto another flight.

Air Canada officials said the airline is doing the best it can to clear up the backlog and has been adding extra flights, bringing in extra crew and flying larger aircrafts.

Travellers trying to make their way by bus were also hitting roadblocks in some parts of Canada.

In Fredericton, which was pounded by a blizzard on Monday, activities at the airport had returned to normal. But bus lines in the province were still struggling to operate on schedule.

Extra buses

Local resident Jennifer Chiasson has been trying since Monday to use Acadian bus lines to get to Moncton for the holidays.

"Hopefully there will be enough room because there was already a bus going to Moncton and it was too full so I have to wait for another one," Chiasson said. "So hopefully I'll get home for Christmas."

The bus line said that it was bringing in extra buses to deal with the backlog but it was also scheduled to switch to reduced routes for the holidays.

Meanwhile, New Brunswick was preparing to be hit with another blast of winter weather, with the forecast projecting freezing rain for parts of the province. In Nova Scotia and parts of Newfoundland, rainfall warnings have been issued.

In the Prairies, the arctic outflow was still freezing the provinces for the second week.

On Wednesday morning, Saskatchewan and P.E.I. were the only provinces for which Environment Canada had not issued weather warnings.
