Environment Canada is advising people to drive carefully because of a thick fog that is blanketing southern Ontario.  A fog advisory has been issued.

Environment Canada says the fog is expected to disperse through the morning. However,  some areas will continue to experience reduced visibility.  Many areas, including Toronto’s Pearson Airport, are also reported to experience less than 200 meters of visibility.

The GTAA announced that because of the weather, “… the flow of arrivals has been reduced by NAV Canada as a result of fog affecting the region. The airport continues to operate, but inbound flights may be delayed.”

According to the GTAA website, a majority of flights scheduled to arrive this morning have been delayed . Toronto Pearson airport has advised passengers to check their flight status with their airline before leaving for the airport.

The weather network also reported that there were around 20 school bus delays and cancellations in the Halton region. The delays primarily impacted schools in Burlington and Oakville.

OPP Highway Safety Division spokesperson Kerry Schmidt advises people driving in the fog to, “Turn on your lights” and adds that drivers do not need to turn their four-way flashing lights unless they are stopped or are a hazard to other motorists.

A mix of sun clouds is expected in Toronto for much of the day after the fog has disappeared with a high of 8C.

However, there is a silver lining to the thick fog.  Kelly Sonnenburg, a meteorologist at the Weather Network, reports that “clear skies and an incoming milder air mass are to blame for the dense fog that has spread into the region.”

“The fog will make way for milder temperatures Thursday afternoon, with daytime highs climbing into the double digits for some in southwestern Ontario and several degrees above seasonal for others,” Sonnenburg adds.

Early Friday, a period of rain is forecast in Southern Ontario; however, the weekend is expected to be full of clear skies and milder temperatures. “Abundant sunshine, windy and mild conditions all return for Saturday,” says the weather network.

A regular pattern of colder temperatures isn’t expected until after December 5th.
