As we move through 2025, Canadian businesses must stay alert to changes in corporate tax policy. From provincial shifts to upcoming federal announcements, understanding the current landscape is key to staying compliant and competitive.
Between April 1 and June 30, 2025, the re-election of a minority Liberal government signaled continued stability in the Canada corporate tax rate 2025, with no major changes proposed.

While the current federal corporate tax rate in Canada hasn’t changed, businesses should stay alert as the upcoming federal budget may introduce corporate tax legislation changes with implications for planning and compliance.
For Canadian companies, especially those navigating multiple jurisdictions, understanding the evolving corporate tax brackets and provincial updates like the Ontario corporate tax rate or the small business company tax rate in Q2 is essential.
By monitoring both legislative and enacted changes, businesses can better align their tax strategy with Canada’s shifting regulatory and economic landscape.
