Canada, allies say they're ready to help secure Strait of Hormuz, but don't say how

Canada has signed on to a joint statement by the leaders of seven countries calling on Iran to immediately cease all attempts to block the Strait of Hormuz to commercial shipping and expressing a readiness to contribute to efforts to reopen the Strait.

The statement does not say how the countries might help, although Defence Minister David McGuinty says Canada is "considering" aiding Iran's neighbours if they seek assistance from the NATO alliance.

Iran has effectively blocked the strait since the U.S. and Israel launched their attack on the country on Feb. 28. About one fifth of the world's oil and gas supply normally moves through the strait.

"The disruption of global energy supply chains constitute a threat to international peace and security," the joint statement said.

"We call for an immediate comprehensive moratorium on attacks on civilian infrastructure, including oil and gas installations."

Canada signed on to the statement shortly after it was published by the U.K., France, Germany, Italy, the Netherlands and Japan. In addition, the leaders say they are ready to "contribute to appropriate efforts to ensure safe passage through the strait."

CBC News has reached out to the prime minister's office to get clarity on what kind of contribution Canada would be in a position to offer.

European countries have thus far indicated they will only get involved in the strait if there are efforts to deescalate the situation and end the strikes.

Iran intensified its attacks on oil and natural gas facilities around the Persian Gulf on Thursday, further sending shock waves through the global economy.

Efforts to bypass the Strait of Hormuz have also been targeted. An Iranian drone hit a Saudi refinery on the Red Sea, which the country had been hoping to use as an alternative exit route.
