Canada will also move its clocks

Yes, the parts of Canada that observe Daylight Saving Time (DST) will make its adjustments along with the United States.

The U.S. government recently passed a law changing the DST parameters from the first Sunday in April and the last Sunday in October to the second Sunday in March and the first Sunday in November.

When the U.S. passed the law, there was some question as to whether Canada will go along. Given the economic relationship, 3-4 weeks with different time zones would have way too unusual.

There are a few anamolies to the DST switch in Canada. In Newfoundland and Labrador, the change is made to Daylight Saving Time at 12:01 a.m. instead of 2 a.m. Also, most of Saskatchewan does not move its clocks, a similar pattern to the American states of Arizona and Hawaii (and until recently, most of Indiana).

The extension of a week has made sense for years to allow an extra hour of light for Halloween trick-or-treaters. Whether the 3 weeks extra on the front end will be helpful remains a debate to be determined.
