Fall is the only season in Canada when you can see such an amazing variety of colors. The late September - early October is the best time to see fall colors. Fall colors can be different in different years. You will see the brightest colors in a fall season when cold nights and rain are followed by some sunny days. When September is warm and dry, so are the colors. They look dull-yellow and dry. In Canada the maple trees turn red in late September. The evergreens (spruces, pines, firs, cedars) are still bright green. Many other trees such as birches and poplars turn yellow and aspens glow orange.
In the fall the wetland grass becomes yellow and also helps colors pop. This photo above I took in central Newfoundland in late September.
Fall colors can be found in the city. I took this photo above in Mount Royal Park or Parc du Mont-Royal in Montreal in early October.
The calm surface of water provides excellent mirror to highlight the colors. Typically you may find water more calm in the early morning. Both photos, the one above and the other below were taken in Algonquin park.
Algonquin Provincial Park is one of the best places in Canada to observe fall colors. I have visited Algonquin park many times over the years, and it always offers excellent views.
The shores of Lake Superior is another excellent place to see fall colors. The Trans Canada Highway runs along the shores of Lake Superior. The views on both sides are amazing in late September. If you are headed in this direction, check out the Agawa Canyon Tour Train. The train departs from Sault Ste. Marie and follows the Agawa Canyon carved by the Agawa River. Check out the Agawa Canyon Train Tour website for more info. This is how the Trans-Canada Highway looks in late September near Lake Superior:
Biking trails offer excellent chance to see fall colors further from inhabited areas. I took the photo below on a 10 kilometer biking trail in Algonquin park. The trail runs in place of a former railroad line, through the wilderness and by the river.
Northern parts of Canada have their special fall colors. This is how the Long Range Mountains in the western side of the Newfoundland Great Northern Peninsula look in the fall:
A tundra landscape has no trees, but small vegetation changes its color too. This is how treeless plains and highlands look near L'Anse aux Meadows, in Northern Newfoundland:
City parks also offer excellent views when leafs change their color. Often you don't have to drive far, a local park may offer some great colors. This is one of the parks in Stratford, Ontario, Canada:
