It's not safe to venture out on the ice in northeastern Ontario, officials say, however some people are already making attempts to do so.

On Sunday, Sudbury Police were called to Long Lake after a man went through the ice while on his dirt bike.

Police say the man was able to make it back to shore, though his bike sank.

The ice is too thin for vehicles to cross at this time, and police aren’t the only officals cautioning people the ice isn’t ready to go on yet.

The Sudbury Trail Plan Association president reiterates it hasn’t been cold enough for the ice to freeze adequately.

“The swamps are still [have] quite a bit of heat in them,” Chuck Breathat said.

“We had a lot of rain this fall, so the swamps are very high, the creeks are high. They’re running quite quickly and we haven’t had enough cold weather to freeze them up yet.

Breathat said he knows what it’s like to sink in a swamp as a few years ago, his snowmobile went through.

“My legs were frozen,” he said. “I was wet from my chest down for several hours. I ended up walking around in the slush.”

Ontario Provincial Police inspector Mark Andrews said he cringes to see snowmobiles on Lake Nipissing already.

He said he thinks the number of people venturing upon thin ice is down, though he noted last spring there were fatalities.

“Four is too many,” he said. “It would be nice to have the rest of 2013 without any tragedy.”

A North Bay towing company reports the cost of retrieving a vehicle may prompt people to think twice — the cost could range between $5,000 to $50,000.
