Made in Canada Ontarioâs economic life began with its natural resources like fur, timber and minerals. Today, natural resources are still an important part of the economy in northern Ontario, while southern Ontario has become a manufacturing centre.

An emergency medical technician (EMT) is a trained professional who responds to emergency medical situations, such as car accidents, fires, or injuries occurring in homes or workplaces. Many assume that all people in this profession are paramedics, but this is not the case.
An electromagnetic pulse (EMP) is an intense burst of electromagnetic (EM) energy caused by an abrupt, rapid acceleration of charged particles, usually electron s. An EMP can contain energy components over a large part of the EM spectrum , from very-low-frequency ( VLF ) radio to ultraviolet ( UV ) wavelength s. A lightning strike produces a localized EMP that gives rise to large electrical current s in nearby wires. A single current surge can damage sensitive hardware such as computers and peripherals. All electronic and communications systems should have some form of protection against the effects of an EMP.
