Security Compliance
ByBit's security record now carries a major asterisk. In February 2025, attackers linked to North Korea's Lazarus Group exploited ByBit's multi-signature wallet transfer process and stole roughly $1.5 billion in Ethereum, the largest crypto theft ever recorded. To ByBit's credit, no customers lost funds: the exchange covered all losses from its own liquidity and replenished reserves within about 72 hours, a crisis response widely considered the best the industry has seen. Still, the breach shows that even cold storage and multisig setups can be defeated. Users can secure their accounts with two-factor authentication via Google Authenticator. ByBit also previously ran into trouble in Canada specifically, paying a roughly $2.5 million penalty to the Ontario Securities Commission in 2022 for operating without registration.
CoinField marketed itself as a highly secure exchange using cold storage, multi-signature wallets and encryption. The regulatory record tells a different story: the OSC found the platform did not have sufficient crypto assets in custody to satisfy investor withdrawal requests and misled both investors and the regulator about why withdrawals were delayed. Whatever its technical security, customer funds were not safe. This is a textbook example of why we recommend holding your own coins in your own crypto wallet rather than leaving them on any exchange.

ByBit suffered the largest crypto hack in history in February 2025 (~$1.5B ETH) but fully reimbursed all affected users. CoinField marketed itself as secure but the OSC found it misled investors about the state of customer funds. Neither platform is relevant to Canadians going forward.
Regulatory Compliance
ByBit exited the Canadian market in 2023 due to Canadian regulations and Canada remains on its restricted jurisdictions list. Notably, ByBit has since obtained licenses elsewhere, including a MiCA license serving the EEA through ByBit EU and a UK relaunch in late 2025, but it has shown no intention of registering with Canadian regulators.
CoinField's FINTRAC registration was ceased, and the company was never registered with Canadian securities regulators. In August 2024, Ontario's Capital Markets Tribunal found it violated securities law through unregistered trading, illegal distribution and misleading investors, and in 2025 it was permanently banned from Ontario's capital markets with over $3 million in combined penalties, disgorgement and costs. CoinField did not participate in the proceedings.
ByBit exited the Canadian market in September 2023 due to Canadian regulations and Canada remains on its restricted jurisdictions list. ByBit paid a roughly $2.5 million OSC penalty for operating without registration in Ontario, then exited all of Canada rather than register.

ByBit paid a roughly $2.5 million OSC penalty and exited all of Canada in September 2023 — not merely "doesn't work in Ontario." CoinField had its FINTRAC registration ceased, was never registered with Canadian securities regulators, and was permanently banned from Ontario's capital markets in 2025 — not "fully compliant with FINTRAC as an MSB."
Customer support
ByBit has a helpful support centre on its website with numerous guides about crypto and how to use the exchange, plus ticket-based and chat support. For Canadians this is academic, since the platform is off-limits entirely.
There is no customer support because there is no company left to contact. Former customers with unfulfilled withdrawals were harmed when the platform collapsed, and the tribunal noted the total harm to investors remains uncertain. If you were affected, you can report your experience to the OSC. If anyone contacts you claiming to recover your lost CoinField funds for a fee, that is a recovery scam, a common second-wave fraud targeting victims of collapsed exchanges.

Neither platform has relevant ongoing support for Canadians. ByBit's support is completely inaccessible to Canadians; CoinField has no support function at all.
Conclusion
From a Canadian perspective, there is nothing to choose between ByBit and CoinField — both are unavailable, and for very different reasons.
ByBit exited Canada on September 30, 2023. If you have legacy funds on ByBit, withdraw to a private wallet — do not transfer directly to a regulated Canadian exchange as the transfer may be blocked.
CoinField is not a legitimate operating exchange. It collapsed in 2023 with unfulfilled customer withdrawals, was permanently banned from Ontario's capital markets in 2025, and impostor scam sites now operate under its name. Avoid any site presenting itself as CoinField. If you were a CoinField customer with unmet withdrawals, report your experience to the OSC. If anyone contacts you offering to recover your funds for a fee, that is a recovery scam.
For Canadians looking for well-regulated alternatives, we recommend Kraken (200+ coins, nationally registered restricted dealer since April 2025), Crypto.com (400+ coins, restricted dealer since May 2025), or NDAX (60+ coins, CIRO investment dealer with a flat 0.2% fee).
