The Federal government is taking all possible steps to make sure that tobacco packing companies reveal appropriate health warnings as are associated with the product inside.

With similar purpose, federal government has recently ordered new and strict labeling rules suggesting that manufacturers must increase the size of graphic health warnings on the packages to 75%.

The idea aims to make people learn more about the hazardous effects that the product actually contains in order lower the number of buyers or any new faces attempting to get one.

But the idea is facing criticism from the tobacco manufacturing companies like Imperial Tobacco Canada, the country's largest tobacco manufacturer and distributor and many more.

Aiming against the new rule book, the company has filed a constitutional challenge on Wednesday in the Ontario Superior Court of Justice urging that the tobacco companies must be allowed to enjoy their right to freedom of commercial expressions.

The new warnings from the federal government state that the consumers' must be provided with full information about the product enabling them to take the best purchasing decisions concerning with their health.

"In choosing to further regulate the legal and already heavily regulated industry, it is clear that the federal government is avoiding the country's No. 1 tobacco problem, the illegal tobacco market - a market that evades all taxes and current regulations and whose products carry no health warnings”, Mr. John Clayton, vice-president of Corporate Affairs at Imperial Tobacco Canada, said in a statement.

But tobacco industries insist that Canadians are well aware of risks that are attached to smoking and increasing warning size on packaging to 75 percent is no solution to stop people from smoking. The companies said that the decision will not lead to any more changes to public awareness and their decision to smoke or not to smoke.

The new rule book has made it mandatory for all the tobacco companies to follow packaging rules by June 19.
