There’s a big Canada Day blowout coming July 1 as the northern nation celebrates its 150th anniversary. 

The Canadian colonies gained independence so placidly, unlike the United States, that Britain’s monarch remains the titular head of state to this day. In fact, Britain only granted Canada full power to write a constitution in 1982. The document lists "freedom of conscience and religion" first among four "fundamental" principles that echo the U.S. Bill of Rights from 191 years earlier.  

This is an ideal moment for reporters to ask experts whether secularized Canada 2017 might show where the United States is headed spiritually (and in some cases, legally). Recently, both Canada and the U.S. have seen a rise in religiously unaffiliated “nones,” 24 percent vs. 20 percent respectively.  

With Protestantism, both nations show remarkable losses for “mainline” churches that have floated leftward. Unlike the U.S. and its array of denominations, Canada was traditionally dominated by only two -- the Anglican Church of Canada, with British colonial status, and the United Church of Canada, an ambitious merger among several traditions.

Government surveys report self-identified Anglicans declined from 2,543,000 to 1,632,000 between 1971 and 2011, and for the United Church from 3,769,000 to 2,008,000.

In-house numbers are even more devastating. The Anglicans’ active membership was only 545,957 in an out-of-date 2007 report. The United Church listed 436,292 in 2014 with average attendance of 144,852. Canada’s Evangelical Protestants are a small if vigorous factor compared with the U.S. situation.

A fifth of today’s Canadians were born elsewhere, versus an estimated 13 percent in the U.S.  Canada’s immigrants, heavily Asian, foster a significant rise of non-Christian religions, and 20 percent report no affiliation versus only 10 percent of the U.S. foreign-born. Many U.S. Spanish-speakers identify with Catholicism or the robust Evangelical minority.
