This isn't quite right. Canada explicitly protects freedom of expression under the Canadian Charter of Rights and Freedoms. Like many countries, however, it places limits on this right, such as restrictions on hate speech outlined in Section 319 of the Criminal Code.
The second part of the claim appears to reference the 2022 freezing of assets linked to some members of the Freedom Convoy, a group of truckers who blockaded highways and bridges in Ottawa to protest COVID-19 lockdowns. According to the Canadian government, the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (PCMLTFA) was applied because the blockade jeopardized more than $390 million in daily trade with the United States. The New York Times reported that funds associated with the protestors were unfrozen shortly after the blockade ended.
It is important to note that the government did not seize anyone’s assets. Instead, temporary measures "froze 219 financial products, flagged 253 Bitcoin addresses tied to protesters and organizers, and led one bank to freeze 3.8 million Canadian dollars held by a payment processor". While some protesters may face longer-term financial consequences through banking institutions—such as reduced access to loans in the future—the government’s actions were limited to temporary freezes, not permanent seizures.
