There are many different types of environmental issues in Canada which include air and
water pollution
Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. ...

Melting of the Arctic and its effects on marine ecosystems
Scientists across the world have already started to notice massive reductions in Canada's

sea ice cover, particularly during the summertime. The shrinking of this ice results in the disruption of the ocean circulation, and changes in climate and weather around the world.
The 2019 ''Canada's Changing Climate Report'', written by scientists from institutions around the globe, states that the impacts of climate change on
Atlantic Canada will be very diverse. One impact is that the sea ice will become thinner and will also form for much shorter periods of the year. And with less sea ice than the region usually gets now, wave seasons will become more intense. Atlantic Canada will see a relative rise in sea levels everywhere - a rise which is estimated to be 75 to 100 cm by the year 2100. Scientists also predict that even if emissions decrease, a 20-cm rise is expected to take place during the course of the next 20 to 30 years.
As the ocean warms and subtropical waters move north, the ocean will become warmer and saltier, and since warmer water holds less oxygen than cooler water, marine ecosystems can suffer and become less sustainable because of this lower oxygen level.
In the journal, ''Science'', which was published in March 2019, it explains that warmer waters could actually increase fish stocks in certain regions, like the

Halibut is the common name for three flatfish in the genera '' Hippoglossus'' and '' Reinhardtius'' from the family of right-eye flounders and, in some regions, and less commonly, other species of large flatfish.
