This is a list of the tallest one hundred structures in Canada, measured from the base to the tallest point. This may refer to the roof top, antenna, spire, mast or as in the case with smokestacks and bridges, the highest structural point.

This list includes buildings, towers, transmission towers, chimneys, bridges, and oil platforms.

There is a separate list for guyed masts since their heights are not fully verifiable and may be inaccurate by several metres. In many cases, measurements are taken to the height of the tallest transmitter rather than the actual highest structural point.

The pinnacle and roof height figures are sourced from SkyscraperPage and/or the Council on Tall Buildings and Urban Habitat (CTBUH). In cases of conflicting data, both heights are listed

Tallest 100 structures in Canada (not including guyed masts)
