* At the publication date, the Department of Finance has not yet released draft legislative proposals on these measures.

The takeaway

The legislation in Bill C‑15 covers a wide range of tax measures, including many technical amendments. Many of these tax measures have been long awaited by taxpayers, such as the SR&ED, accelerated CCA and clean economy ITC measures, as well as repealing the DSTA. With only a few weeks remaining before Parliament adjourns for the winter break, it is unclear whether Bill C‑15 will be enacted in 2025 or early 2026. Nevertheless, it is advisable that taxpayers learn about these changes, determine whether any could apply (or benefit) them and start preparing for their implementation.

 

1 This tax credit is consequential to the decrease in the lowest marginal personal income tax rate from 15% to 14.5% for 2025, and then to 14% for 2026, which will be implemented by Bill C‑4, An Act respecting certain affordability measures for Canadians and another measure (first reading: June 5, 2025; waiting for third reading in the House of Commons). This tax credit will ensure that individuals with amounts eligible for non‑refundable tax credits exceeding the first income tax threshold will not have their tax liability increased because of the tax rate decrease.
