Transport Canada has officially certified General Dynamics' Gulfstream G500 and G600 business jets, marking a significant step for the Canadian aviation industry. This certification comes in the wake of U.S. President Donald Trump's threats to decertify Canadian-built planes if the Canadian government did not expedite the approval process for Gulfstream jets. The certification date for the G500 and G600 was recorded as February 15, indicating a swift response from Canadian authorities following Trump's comments.
