In Canada there is the Canadian Geothermal Energy Association (CanGEA) that is the collective voice of Canada’s geothermal energy industry. This is usually a non-profit industry association that represent the interests of its member companies with the primary goal of unlocking the country’s tremendous geothermal energy potential.read more here!

The potential for geothermal energy in Canada is immense; it is estimated to be well over 5,000 MW by CanGEA, in shallow depth geothermal resources with currently available technology and technology that can be easily transferred from the Oil & Gas, Mining Canadian industries that are already in place.
Also the geothermal energy is used in geothermal heating that is the direct use of geothermal energy for heating applications.
The Geothermal energy originates from the heat retained within the Earth. Most high temperature geothermal heat is harvested in regions close to tectonic plate boundaries (e.g. Canada) where volcanic activity rises close to the surface of the Earth. In these areas, ground and groundwater can be found with temperatures higher than the target temperature of the application. But even cold ground contains heat and it may be extracted with a heat pump (Ground
Source Heat Pump).
In regions without any high temperature geothermal resources, a (GSHP) can provide space heating and space cooling. Like a refrigerator or air conditioner, these systems use a heat pump to force the transfer of heat from the ground to the building. Heat can be extracted from any source, no matter how cold, but a warmer source allows higher efficiency. A ground-source heat pump uses the shallow ground or ground water.
GSHP merely accesses stored solar heat energy in the soil or rock.
GSHPs circulate a carrier fluid through closed pipe loops buried in the ground. As the fluid circulates underground it absorbs heat from the ground and, on its return, the warmed fluid passes through the heat pump which uses electricity to extract heat from the fluid. The re-chilled fluid is sent back into the ground thus continuing the cycle. The heat extracted and that generated by the heat pump appliance as a byproduct is used to heat the house. The addition of the ground heating loop in the energy equation means that significantly more heat can be transferred to a building than if electricity alone had been used directly for heating.
Although there are no major geothermal plants in Canada there are various companies that offer geothermal services like drilling and others.
