Canadian equities saw a decline following Prime Minister Mark Carney's announcement of an expanded investment tax write-off. The measure, unveiled during an investment summit in Toronto, adds oil and gas pipelines, mining property, and other assets to the list of eligible items for accelerated deductions in Canada. This move is part of a broader strategy by Carney's government to attract C$1 trillion ($721 billion) in investments over five years, as Canada seeks to diversify its markets and reduce reliance on the US, especially amid escalating trade tensions.

The investment summit, hosting dozens of firms and top global investors like Larry Fink of BlackRock, Inc. and Jon Gray of Blackstone Inc., aims to showcase 167 projects across various sectors. These opportunities range from shovel-ready developments to early-stage planning, encompassing data centers, critical-mineral mines, high-speed rail, and an Arctic trade corridor. Over half of these projects are concentrated in energy and mining, highlighting the government's priorities in these areas.

The expansion of the tax break is intended to make Canada a more attractive destination for global capital. While the move is designed to stimulate investment and economic growth, the immediate market reaction was negative for Canadian equities. This suggests investor uncertainty or a mixed reception to the policy changes and the broader economic strategy being pursued by the Carney government.
