RCAF Station Winisk
Royal Canadian Air Force Station Winisk (RCAF Station Winisk) was a military installation located in Winisk, Ontario. RCAF Winisk was one of eight Sector Control Stations on the Mid-Canada Line system of radar stations. Each SCS received signals from a series of unmanned detection sites located approximately 50 km apart. In Winisk, radio wave signals were transmitted along the chain of stations to the SCS, then to MCL Site 070 Mount Kempis via tropospheric scatter system and finally to RCAF Station North Bay by land line. As there is no road or rail access to Winisk, an airstrip was also built to serve the base (and still exists on the site). Opened in 1957, and fully operational in 1958, RCAF Station Winisk was in operation for just eight years. The eastern portion of the Mid-Canada Line was shut down in 1965 and the Winisk base was closed. Buildings and roads on the site remain.

Mid-Canada Line
The Mid-Canada Line (MCL), also known as the McGill Fence, was a line of radar stations running east–west across the middle of Canada, used to provide early warning of a Soviet bomber attack on North America. It was built to supplement the Pinetree Line, which was located farther south. The majority of Mid-Canada Line stations were used only briefly from the late 1950s to the mid-1960s, as the attack threat changed from bombers to ICBMs. As the MCL was closed down, the early warning role passed almost entirely to the newer and more capable DEW Line farther north. The MCL was based on the bistatic radar principle, using separated transmitters and receivers. An aircraft flying anywhere between the stations would reflect some of the transmitted signal towards the receiver, where it would mix with the signal travelling directly from the transmitter. The mixing of the two signals produces a pattern that is very easy to detect using simple electronics. As the transmitter is not pu ...

Winisk, Ontario
Winisk 90 is a First Nation reserve and ghost town in the Kenora District in Northern Ontario, situated along the Winisk River. It was destroyed in the 1986 Winisk Flood. After the flood, the residents of the Weenusk First Nation were forced to re-locate to Peawanuck, 30 km inland. Winisk was home to Royal Canadian Air Force Station Winisk, a Mid-Canada Line radar control station from 1958 to 1965. The town was served by Winisk Airport (YWN) via a 6,000 feet plus gravel runway which can still be seen. In 1964, Transair (Canada) was operating scheduled weekly roundtrip passenger flights with Douglas DC-4 propliners on a Montreal - Ottawa Ottawa (, ; Canadian French: ) is the capital city of Canada.

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and ...

Mid-Canada Line Site 070 Kempis
Mid-Canada Line Site 070 Kempis was a part of the Mid-Canada Line air defence network. During the late 1950s, the Mid-Canada Line (MCL) was developed as a secondary line of detection in case enemy aircraft penetrated the Distant Early Warning Line. This consisted of approximately 90 unmanned sites and eight Sector Control Stations located along the 55th parallel. Each site sent out a radio beam to its neighbouring site. If an aircraft interrupted the beam, an intruder alarm would sound. Mount Kempis (near CFS Ramore) was chosen as a relay station for signals coming in from the Sector Control Site at RCAF Station Winisk. The signals would be sent to Mount Kempis via a Tropospheric scatter system and then they would forward the signals via a land-line to the RCC at RCAF North Bay. This required the installation of a large parabolic antenna to receive the signals. MCL Site 070 ceased operations as a troposcatter Tropospheric scatter, also known as troposcatter, is a method of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RCAF Station North Bay

Member Of Parliament
A member of parliament (MP) is the representative in parliament of the people who live in their electoral district. In many countries with Bicameralism, bicameral parliaments, this term refers only to members of the lower house since upper house members often have a different title. The terms Member of Congress, congressman/congresswoman or Deputy (legislator), deputy are equivalent terms used in other jurisdictions. The term parliamentarian (other), parliamentarian is also sometimes used for members of parliament, but this may also be used to refer to unelected government officials with specific roles in a parliament and other expert advisers on parliamentary procedure such as the Senate Parliamentarian in the United States. The term is also used to the characteristic of performing the duties of a member of a legislature, for example: "The two party leaders often disagreed on issues, but both were excellent parliamentarians and cooperated to get many good things done." ...

Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowl ...

Polychlorinated Biphenyl
Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by the Stockholm Convention on Persistent Organic Pollutants in 2001. They are organic chlorine compounds with the formula C12 H10−''x'' Cl''x''; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the 1960s, when a host of problems were identified. With the discovery of PCBs' environmental toxicity, and classification as persistent organic pollutants, their production was banned by United States federal law in 1978, and by the Stockholm Convention on Persistent Organic Pollutants in 2001.

Radar Networks
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. The t ...
